The scientific method is an approach used to investigate a scientific problem and consists of several key steps: (1) asking a question and conducting research; (2) developing a hypothesis; (3) performing experiments to test the hypothesis; (4) collecting and analyzing data from the experiments; and (5) sharing results and developing a theory or law to explain the findings. The scientific method relies on objective measurement and evidence from experiments in which variables are controlled to test hypotheses and develop theories.

Science involves researching and trying to explain the natural world through direct observation or using tools. The scientific method includes stating the problem, researching existing knowledge, developing a hypothesis, designing experiments to test the hypothesis, collecting and analyzing data, organizing the results, and sharing findings with others. A hypothesis or theory must be testable and able to be modified as new evidence is found. While science seeks to understand nature, it does not determine how its findings should be applied - that role belongs to society.
Scientific revolution and age of reason
The document provides information about a lesson on the Scientific Revolution and the Age of Reason, including:
1) Key figures of the Scientific Revolution such as Copernicus, Kepler, Galileo, Newton, and Harvey and their accomplishments that changed views of the world.
2) The significance of the Scientific Revolution in emphasizing reason and systematic observation of nature.
3) Developments during the Age of Reason including new forms of art, literature, music, and technologies that improved life and stimulated trade.
Progress in science
1. Thomas Kuhn argued that science does not progress smoothly but rather goes through periods of normal science punctuated by scientific revolutions.
2. During normal science, most scientists work within the dominant paradigm without questioning it, while scientific revolutions occur when the prevailing paradigm is rejected in favor of a new way of understanding.
3. Kuhn's view challenged the idea that science progresses linearly towards objective truths, and sparked debate about the nature of scientific progress and rationality in theory change.
Scientific Revolution Unit 3 Topic 1 Honors World
The document discusses the impact of the Scientific Revolution on political thought. It describes how figures like Copernicus, Galileo and Newton developed early scientific models that challenged the authority of the Catholic Church. Philosophers like Descartes, Hobbes and Locke then incorporated these new scientific ideas, believing that reason and natural laws could be used to explain both the natural world and human society. The Scientific Revolution emphasized observation and experimentation over religious doctrine and helped shift authority from the Church to science and reason.
The Scientific Revolution
The Scientific Revolution was driven by several major factors in the 16th-17th centuries including the rise of universities, recovery of classical texts, and individuals being able to pursue scientific investigation with patronage. Copernicus proposed a heliocentric model of the universe, with the sun at the center, challenging the Ptolemaic geocentric view. Kepler formulated the laws of planetary motion providing mathematical proofs for the heliocentric theory. Galileo provided further evidence for heliocentrism through his astronomical observations with an improved telescope. Newton later synthesized the works of Copernicus, Kepler, and Galileo by formulating the law of universal gravitation, proving the universe followed precise mathematical relationships.
The scientific revolution
The document discusses key figures of the Scientific Revolution from the 15th to 17th centuries who helped transition Europe from doctrinal passivity to an emphasis on scientific inquiry and experimentation. It describes the contributions of Copernicus, Kepler, Galileo, Descartes, Newton, Bacon, Harvey, and Einstein. Their works challenged prior assumptions, established new methodologies like the scientific method, and laid the foundations for modern science in fields like astronomy, physics, mathematics, and medicine.
Thomas Kuhn & Paradigms (By Kris Haamer)
Thomas Kuhn was a physicist and philosopher known for his work "The Structure of Scientific Revolutions" which introduced the concepts of paradigms and paradigm shifts. A paradigm is a universally accepted scientific theory that provides models and solutions for a community of scientists. According to Kuhn, normal science operates within an existing paradigm until anomalies emerge that cannot be explained, creating a crisis and leading to a new paradigm that better explains the facts. This process of paradigm shifts advances scientific understanding as new theories provide more accurate ways of viewing reality.
The Scientific Revolution V2007
1) Prior to the Scientific Revolution, most Europeans believed in the geocentric model that the Earth was at the center of the universe.
2) Copernicus, Kepler, Galileo and Newton helped establish the heliocentric model through observations, experiments, and mathematical laws.
3) The Scientific Revolution established the modern scientific method and fundamentally changed how people understood the universe.

It is the key to unlock the bodies of knowledge by helping the researcher in organizing his or her thoughts and procedures and making him or her confident of the findings from the expirements
COMPONENTS OF A SCIENTIFIC INVESTIGATION
1. Statement of the Problem
-You should have existing knowledge of the problem
This part answers the following questions:
What questions do you have about your topic?
What do you want to know?
EXAMPLE
How does fertilizer affect the growth of plants?
2. Formulation of Hypothesis
Hypothesis-simple statement that presents the possible solution to the problem. It can be tested, and it is based on knowledge and research.
Hypothesis may be stated in two ways:
a. Null Hypothesis (Ho)-states that no relationship between variables
Example: The fertilizer DOES NOT affect the growth of plants
b. Alternative hypothesis (Ha)-states a relationship between variables
Example: There is significant relationship between the growth of plants and the use of fertilizer
Ha2 : There is a negative relationship between A and B
(Less A is involved, the better B)
Ha3 There is a positive relationship between A and B.
(More B is involved, the better A)
3. Testing Hypothesis and Gathering of Data
Experiments-a set of manipulations or specific observations of nature, and it is considered the most important part of the scientific method.
Three Types of Experiments
1. Controlled Experiment-the observer tests the hypothesis by looking for changes brought by alteration to a variable
Variable- a characteristic, number, or quantity that increases or decreases over time or takes different values in different situations.
a. Controlled variables-variables that are kept constant.
b. Independent variables-factors that you change or alter during the experiment.
c. Dependent variables-variables that you observe. and they are considered the response to an independent variable
2. Natural experiments or quasi-experiments-Here, the observer does not manipulate any variable but simply collects all the possible data to determine the factors affecting a particular phenomenon.
3. Field experiment-named to draw a contrast with laboratory experiments. It examines the real world using scientific method.
Example: Political sciences, economics, and psychology
Prediction
a forecast of future events based on past observations.
Example: The plants will grow faster and strong
Science and the Scientific Method
Science involves the systematic study of nature and its rules through observation and experimentation. The most basic science is physics, which deals with concepts like motion, forces, energy, and matter. Technology applies scientific knowledge to practical problems. The scientific method uses educated guesses called hypotheses, experiments, and conclusions to build knowledge about the natural world. Key aspects of the scientific method include forming hypotheses, making predictions, designing experiments to test predictions, analyzing data, and drawing conclusions.
Chp. 1.1 1.2 notes
Scientific thinking begins with making observations of natural phenomena in a careful, systematic manner. These observations produce data that can be quantitative (expressed as numbers) or qualitative (descriptive characteristics). Scientists use data to make inferences and propose hypotheses, which are testable scientific explanations. The scientific method involves identifying a problem, researching it, proposing hypotheses, designing experiments to test hypotheses, analyzing results, and drawing conclusions. Experiments aim to test only one variable at a time and identify independent and dependent variables. Repeating experiments allows scientists to determine if results can be reproduced, establishing theories that unify broad evidence. Scientific theories and laws enable predictions but may be revised as new evidence emerges.

The Scientific Method
Steps in the Scientific Method
There is a great deal of variation in the specific techniques scientists use explore the natural world. However, the following steps characterize the majority of scientific investigations:
Step 1: Make observations
Step 2: Propose a hypothesis to explain observations
Step 3: Test the hypothesis with further observations or experiments
Step 4: Analyze data
Step 5: State conclusions about hypothesis based on data analysis
Each of these steps is explained briefly below, and in more detail later in this section.
Step 1: Make observations
A scientific inquiry typically starts with observations. Often, simple observations will trigger a question in the researcher's mind.
Example: A biologist frequently sees monarch caterpillars feeding on milkweed plants, but rarely sees them feeding on other types of plants. She wonders if it is because the caterpillars prefer milkweed over other food choices.
Step 2: Propose a hypothesis
The researcher develops a hypothesis (singular) or hypotheses (plural) to explain these observations. A hypothesis is a tentative explanation of a phenomenon or observation(s) that can be supported or falsified by further observations or experimentation.
Example: The researcher hypothesizes that monarch caterpillars prefer to feed on milkweed compared to other common plants. (Notice how the hypothesis is a statement, not a question as in step 1.)
Step 3: Test the hypothesis
The researcher makes further observations and/or may design an experimentto test the hypothesis. An experiment is a controlled situation created by a researcher to test the validity of a hypothesis. Whether further observations or an experiment is used to test the hypothesis will depend on the nature of the question and the practicality of manipulating the factors involved.
Example: The researcher sets up an experiment in the lab in which a number of monarch caterpillars are given a choice between milkweed and a number of other common plants to feed on.
Step 4: Analyze data
The researchersummarizes and analyzes the information, or data, generated by these further observations or experiments.
Example: In her experiment, milkweed was chosen by caterpillars 9 times out of 10 over all other plant selections.
Step 5: State conclusions
The researcher interprets the results of experiments or observations and forms conclusions about the meaning of these results. These conclusions are generally expressed as probability statements about their hypothesis.
Example: She concludes that when given a choice, 90 percent of monarch caterpillars prefer to feed on milkweed over other common plants.
Often, the results of one scientific study will raise questions that may be addressed in subsequent research. For example, the above study might lead the researcher to wonder why monarchs seem to prefer to feed on milkweed, and she may plan additional experiments to explore this question. For example, perhaps the milkweed has higher ...
Lecture 1.1 & 1.3- What is Chem?
Chemistry is the study of matter and the changes matter undergoes. Matter is anything that has mass and takes up space. The scientific method is a systematic process used to solve scientific problems and involves making observations, developing hypotheses to explain observations, designing experiments to test hypotheses, and developing theories based on experimental evidence. A hypothesis is a proposed explanation for an observation that can be tested in an experiment, where the independent variable is manipulated and the dependent variable is measured. Repeated experimental evidence can lead a hypothesis to become a scientific theory or law.
Scientific Method
The document outlines the steps of the scientific method which include:
1) Developing a question or problem
2) Making observations and researching the topic
3) Predicting a possible answer in the form of a hypothesis
4) Developing and following a procedure for an experiment
5) Collecting and analyzing results and modifying the procedure if needed
6) Stating whether the hypothesis is accepted or rejected based on conclusions
7) Communicating the results to others
Introduction to Science and Chemistry
1. Science is a way of exploring and explaining the natural world using a process designed to reduce errors. It consists of various disciplines that study either physical phenomena like physics and chemistry or living organisms like biology.
2. The scientific method involves making observations, asking questions, developing hypotheses, making predictions, testing predictions through experiments, analyzing results, and peer reviewing findings. It allows scientific understanding to advance through evaluation and dissemination of information.
3. Scientific theories are hypotheses that have been rigorously tested and accepted as generally correct, but cannot be proven absolutely. Laws summarize scientific facts about nature. The body of scientific knowledge is stable but open to improvement through testing.

The scientific method involves observing phenomena, formulating hypotheses to explain observations, experimentally testing hypotheses, and communicating results. It begins with making qualitative or quantitative observations of a system, followed by proposing a hypothesis to explain the observations. Experiments are then conducted to test the hypothesis, and theories may be developed that are supported by experimental evidence. Results are shared with the scientific community.
The science of biology blackboard
Science is an organized way to use evidence and study the natural world. Biology is the study of life, and living things share certain characteristics - they are made of cells, can reproduce, have genetic material, grow and develop, obtain and use energy, respond to stimuli, regulate homeostasis, and evolve over time. The scientific method is used to study the natural world through questioning, researching, hypothesizing, experimenting, analyzing results, and drawing conclusions.

Here is how I would design the experiment:
- Control Group: 2 patients who do not receive the drug. This group acts as the standard for comparison.
- Experimental Group: 4 patients who receive the new drug.
- Independent Variable: Whether or not the patient receives the new drug. This is what is being manipulated.
- Dependent Variable: The growth of breast cancer in the patients, as measured by tumor size. This variable depends on and is expected to change due to the independent variable.

3. The results disprove the initial hypothesis that medium concentration would be best, and instead indicate that a weak concentration allows maximum growth.
Scientific Method
The scientific method involves observing phenomena, formulating hypotheses to explain observations, experimentally testing hypotheses, and communicating results. It begins with making qualitative or quantitative observations of a system, followed by proposing a hypothesis to explain the observations. Experiments are then conducted to test the hypothesis, and theories may be developed that are supported by experimental evidence. Results are shared with the scientific community.
The science of biology blackboard
Science is an organized way to use evidence and study the natural world. Biology is the study of life, and living things share certain characteristics - they are made of cells, can reproduce, have genetic material, grow and develop, obtain and use energy, respond to stimuli, regulate homeostasis, and evolve over time. The scientific method is used to study the natural world through questioning, researching, hypothesizing, experimenting, analyzing results, and drawing conclusions.
The Nature of Science.ppt
Here is how I would design the experiment:
- Control Group: 2 patients who do not receive the drug. This group acts as the standard for comparison.
- Experimental Group: 4 patients who receive the new drug.
- Independent Variable: Whether or not the patient receives the new drug. This is what is being manipulated.
- Dependent Variable: The growth of breast cancer in the patients, as measured by tumor size. This variable depends on and is expected to change due to the independent variable.

Gtscimeth
The document discusses the scientific method and provides several key points:
1) There is no single scientific method, as scientists use many approaches and reasoning techniques borrowed from other fields.
2) The scientific method is often oversimplified as a set of rigid steps, but science actually progresses through trial and error.
3) The most important aspects of the scientific method are making observations, forming hypotheses, designing experiments to test hypotheses, analyzing results, and subjecting findings to peer review. This process aims to ensure experiments produce reliable answers to specific questions.

Frog review
This document provides a diagram labeling various anatomical features of an animal's internal organs and systems, including the location of the vomerine teeth, gullet, internal nares, glottis, maxillary teeth, vocal sacs, eye sockets, tympanic membrane, nictitating membrane, external naris, liver, fat bodies, small intestine, heart, gall bladder, lungs, kidneys, spleen, cloaca, mesentery, stomach, testis, urinary bladder, ovaries, oviduct, and their relative positions.
Chpt.3.1
1) Arthropods undergo either complete or incomplete metamorphosis. Complete metamorphosis involves four stages: egg, larva, pupa, and adult. Incomplete metamorphosis involves hatching from eggs as nymphs and molting into winged adults after several molts.
2) Animals exhibit one of three types of symmetry: asymmetry, radial symmetry, or bilateral symmetry. Radial and bilateral symmetry involve dividing the animal into mirror halves, while asymmetry does not.
3) Succession describes the process of ecological community change over time. There are two types: primary succession colonizes new bare rock and soilless sites, while secondary succession occurs on existing soil after a disturbance like
Chpt.2.3
This document summarizes the cycling of important materials like water, carbon, nitrogen, and phosphorus through ecosystems. It explains that while energy is lost at each trophic level, the sun replenishes it, and matter is recycled as nutrients move through organisms. The atoms that make up living things today have been on Earth since life began. It then provides more detailed explanations of the water, carbon, nitrogen, and phosphorus cycles.
Chpt.2.2
The flow of energy in an ecosystem begins with autotrophs, such as plants, which use energy from the sun to produce their own food through photosynthesis. Heterotrophs, including herbivores, carnivores, omnivores, and decomposers then obtain energy by consuming autotrophs and other organisms. This energy is transferred between trophic levels in a food chain and food web, with less energy being available at higher trophic levels due to energy being lost as heat at each transfer.
Chpt.2.1
Ecology is the scientific study of the interactions between organisms and their environments. It reveals the interrelationships between living (biotic) and nonliving (abiotic) parts of the world. Key concepts in ecology include the biosphere, biotic factors, abiotic factors, levels of organization (organism, population, community, ecosystem, biome, biosphere), habitats, niches, and symbiosis (commensalism, mutualism, parasitism). Ecology combines information from various sciences to understand these relationships.
Chpt. 17.3- Domains and Kingdoms
The document discusses different systems for classifying life into kingdoms and domains. It describes the three domain system of Bacteria, Archaea and Eukarya. It also outlines the six kingdom system of Bacteria, Archaea, Protista, Plantae, Fungi and Animalia. Finally, it mentions the traditional five kingdom system of Monera, Protista, Plantae, Fungi and Animalia. It provides details about the defining characteristics of each domain and kingdom.
Chpt. 17.2 Modern Classification
Cladograms are branching diagrams that represent the proposed evolutionary history of a species or group, with closer branches indicating that organisms have more traits in common. They are a modern method of classification that shows evolutionary relationships rather than just taxonomic rankings.
Chpt. 17.1-History of Classification
Aristotle first classified organisms as either animals or plants, with plants grouped by size and animals by whether they had blood. Linnaeus broadened Aristotle's system and created the first formal taxonomy, grouping organisms into a binominal nomenclature with a genus and species name. The taxonomic categories from most specific to broad are species, genus, family, order, class, phylum, kingdom, and domain.
Chpt.15.2-Evidence of Change
There are several ways that scientists provide evidence of evolution, including comparative anatomy, comparative embryology, and fossils. Comparative anatomy looks at homologous and analogous structures between species, while comparative embryology examines similarities in development. Fossils provide direct evidence of extinct species and how they changed over time. Scientists use both relative dating of fossils layers and radioactive dating to determine the age of fossils and track changes in species. Adaptations like camouflage and mimicry help organisms survive and reproduce more successfully.
Chpt. 15.1
Charles Darwin developed the theory of evolution by natural selection based on his observations as a naturalist aboard the HMS Beagle in the 1830s. While visiting the Galapagos Islands, Darwin noticed that related but distinct animal species inhabited different islands. He later concluded that populations on the mainland evolved over generations as they adapted to their local environments, with better adapted traits being passed down. Darwin's theory proposed that natural selection drives evolution, as organisms better suited to their environment will survive and reproduce, passing on their favorable traits.
Chapter 11.3 notes
A karyotype is a micrograph that arranges homologous chromosome pairs in decreasing size order. It is used to study chromosomes stained during cell metaphase. Nondisjunction is a cell division error where sister chromatids do not separate properly, which can cause conditions like Down syndrome.
Chpt. 11.2 complex inheritance leftovers
Sickle-cell anemia is an autosomal recessive trait common in those with African and Mediterranean ancestry. It causes abnormally shaped red blood cells, impaired blood flow, tissue damage, and health issues. Sex is determined by the 23rd pair of chromosomes - females have XX and males have XY. The X chromosome carries many genes needed for development in both sexes. To compensate for having two X chromosomes, females inactivate one randomly. Sex-linked traits are on the X chromosome and are always expressed if recessive in females. Muscular dystrophy is an X-linked recessive disease. Polygenic traits like skin and eye color are influenced by two or more genes and result in a range of intermediate phenotypes.
Chapter 11.1 notes
This document summarizes several human genetic disorders including their inheritance patterns, symptoms, prevalence, and treatment options. Huntington's disease is an autosomal dominant neurological disorder with onset between 30-50 years of age that is always fatal. Cystic fibrosis is the most common lethal genetic disorder among white Americans, affecting the lungs and digestive system due to thick mucus production, with current treatments improving life expectancy. Tay-Sachs disease causes neurological deterioration and death by age 5 due to fatty acid accumulation in the brain.
Incomplete codominance multiple_alleles
The document discusses different patterns of inheritance beyond simple dominance:
1) Incomplete dominance, where the heterozygous phenotype is intermediate between the homozygous phenotypes. Examples include snapdragons and carnations.
2) Codominance, where both alleles are expressed in the heterozygote rather than blending. Examples include checkered chickens, roan horses, and variegated clover.
3) Multiple alleles, where more than two alleles control a trait. Examples include human blood types and coat colors in rabbits.
10.2 mendelian genetics
Gregor Mendel conducted the first scientific studies of heredity by breeding pea plants. He found that traits are transmitted from parents to offspring through discrete units called alleles. Through his experiments with monohybrid and dihybrid crosses, Mendel established the laws of segregation, dominance, and independent assortment. These laws describe the basic principles of genetic inheritance and provided the foundation for the modern science of genetics.
Chapter 12.4 gene regulation & mutation
This document summarizes gene regulation and mutation. It explains that gene regulation allows organisms to control which genes are transcribed in response to the environment, using operons in prokaryotes. Mutation is a change in the DNA sequence that can cause changes in proteins. There are two main types of mutations: point mutations which substitute a single nucleotide, and frameshift mutations which insert or delete nucleotides, affecting all subsequent amino acids. Mutations can be caused by environmental factors like radiation or chemicals and may be passed to offspring.
Chapter 12.3 dna,rna and protein
DNA contains the genetic code that is transcribed into messenger RNA (mRNA) which is then translated into proteins. There are three main types of RNA - mRNA carries the genetic code from DNA to the ribosome for protein production. Ribosomal RNA (rRNA) helps join mRNA to transfer RNA (tRNA) during protein synthesis. TRNA transports amino acids to the ribosome where they are linked together based on the mRNA codon sequence.
Chapter 12.2 dna replication
DNA replication is a semiconservative process where the parental DNA strands separate and each serves as a template to produce two new DNA molecules, each with one original and one new strand. It occurs in three stages: unwinding, base pairing, and joining. During unwinding, enzymes separate the double helix and add RNA primers. Then, DNA polymerase adds complementary bases to each new strand by matching A-T and C-G. The lagging strand replicates in fragments that are later joined.
Chapter 12.1 molecular genetics
The document summarizes early discoveries about DNA and its structure. Frederick Griffith discovered transformation could occur between bacterial strains. Avery, MacLeod and McCarty showed that DNA was the transforming molecule. Hershey and Chase provided evidence that DNA, not protein, was the genetic material of viruses. Chargaff discovered base pairing rules for DNA. Rosalind Franklin and Maurice Wilkins used X-ray crystallography to study DNA structure. Watson and Crick then proposed the double helix model of DNA structure based on Chargaff's rules and Franklin and Wilkins' research.
Meiosis
Meiosis is a type of cell division that produces gametes, such as sperm and egg cells, with half the normal number of chromosomes. It involves two cell divisions: Meiosis I and Meiosis II. In Meiosis I, homologous chromosomes pair up and separate, reducing the chromosome number by half. Meiosis II then separates the sister chromatids, resulting in four haploid daughter cells each with a single set of chromosomes. This ensures genetic variation and allows for sexual reproduction where gametes from two individuals combine to form a diploid zygote.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
GNSS spoofing via SDR (Criptored Talks 2024)
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.
Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
