Physical Science Chapter 1.1 What is Physical Science?
Physical science is the study of matter, energy, and the changes they undergo through observation and logical reasoning. It involves using skills like making observations both qualitative and quantitative, inferring interpretations based on observations and prior knowledge, and predicting what will happen in the future based on past evidence. The two main branches are chemistry, which studies the properties of matter and how it changes, and physics, which studies matter, energy, motion, and the forces that interact between them. Key concepts of physical science include force, energy, conservation, atomic theory, and the behavior of particles in different states of matter.

The document discusses several key aspects of the nature of science:
1. Science aims to understand the natural world through careful methodology like observing, measuring, and experimenting. Scientific knowledge is also shaped by human creativity and logic.
2. Scientific theories are substantiated explanations that are continually tested against evidence. Laws summarize relationships demonstrated by evidence.
3. While scientific knowledge is durable, it is also subject to change as new evidence emerges. Scientists try to avoid bias and ensure validity through practices like peer review.
4. Science is influenced by social and political factors as research requires funding and support that can change over time and between cultures. The history of stem cell research is one example.
Intro to Physical Science (Grade 8: Class B ONLY)
This document provides an overview of science and the scientific method. It defines science as a systematic way of learning about the natural world, with three main branches: life science, earth science, and physical science. Physical science is further divided into chemistry and physics, focusing on the study of matter, energy, and their interactions. The scientific method is then described as a logical process used by scientists involving observation, developing a hypothesis, experimentation, analysis of data, and forming a conclusion. Well-tested conclusions may become scientific theories that explain natural processes.
Science and environment
Science involves observing, studying, and experimenting to understand nature. Scientists investigate, plan experiments, observe results, and test theories. There are many branches of science, including physical, earth, and biological sciences. Science and technology work together, with science exploring nature through experimentation and technology applying scientific knowledge to improve human lives. The environment includes all surrounding factors that affect living things, and consists of both biotic elements like plants and animals as well as abiotic elements such as air, water, and soil. Ecosystems link biotic and abiotic components through energy and nutrient cycles.
Grade 62 nd
This document outlines 10 scientific attitudes that are important for solving problems:
1. Careful judgment based on facts rather than jumping to conclusions.
2. Creativity in generating original ideas and uncommon solutions.
3. Critical mindedness in evaluating evidence and prioritizing accuracy over other factors.
4. Curiosity in continually learning and understanding why and how things work.
Chapter 2, Section 2
1) An estimate is an approximation of a number based on reasonable assumptions, not a guess. Scientists rely on estimates when exact numbers cannot be obtained.
2) Accuracy refers to how close a measurement is to the true value, while precision refers to how close repeated measurements are to each other. Scientists aim for both accuracy and precision.
3) There are several ways to calculate an average - the mean, median, and mode. The mean is the sum of all values divided by the total number. The median is the middle number. The mode is the most frequently occurring number.
Chapter 2, Section 1
The document discusses the International System of Units (SI) as the standard measurement system used by scientists. It describes the basic SI units for measuring length, mass, volume, time, and temperature. For each measurement, it provides the standard unit and any smaller or larger units used. For example, the basic SI unit for length is the meter, but smaller lengths are measured in centimeters or millimeters and larger distances in kilometers. This allows scientists to precisely measure quantities and communicate results using a common language of measurement.
Scientist attitudes
Scientists follow a scientific method that involves being open-minded, skeptical, and intellectually honest. The scientific method is a process for building an accurate model of reality through observation, measurement, classification, quantification, inference, prediction, identifying relationships between variables, interpreting data, and controlling variables. It involves making observations and measurements, grouping objects, using numbers to express observations, generating explanations, projecting future events based on evidence, analyzing interactions between factors, recognizing patterns in data, and isolating single influences.

Scientists test hypotheses through controlled experiments where they manipulate one variable while keeping all others the same to observe the responding variable. If evidence from many investigations supports a hypothesis, it may become accepted as a theory, which provides a well-tested explanation that unifies various observations. Controlled experiments allow scientists to determine the effect of changing a single factor by isolating the manipulated, or independent, variable from other influences.

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.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

- 2. Science is Everywhere Science is the systematic study of natural events and conditions. Scientists ask questions that can be measured. • Empirical evidence is evidence gained from observations and measurements.
- 3. Scientific Knowledge Scientific Theory – a well supported explanation about the natural world. Ex. Plate Tectonics, Evolution, Scientific Law- describes a basic principle of nature that always occurs under certain conditions. Ex. Law of superposition, Law of Gravity Science is durable (able to last throughout the years) because it is
- 4. Scientific Investigations Hypothesis – a testable explanation that leads to a scientific investigation. Independent Variable (testing variable) – the 1 factor that is changed in an experiment. Dependent Variable (outcome variable)- the factor that responds to a change of the I.V. (recorded as DATA) All Scientific Investigations involve making observations about the natural world.
