Physical Science 1.1 : What is Matter?
Matter is anything that has mass and takes up space. There are two key properties of matter: volume, which is the amount of space an object takes up and is measured in liters or milliliters, and mass, which is the amount of matter in an object and is measured in kilograms. Mass is constant for an object no matter its location, while weight depends on location and gravity. An object's mass determines its inertia, or resistance to changes in motion - the more mass, the greater the inertia.

4. The process of converting between different units used to measure the same quantity, using conversion factors like those to change between kilograms and pounds
Physical Science 1.2 : Physical Properties
Physical properties can be observed or measured without changing the identity of matter and include density, which is the amount of matter in a given volume. Density can be used to identify substances and is calculated by dividing an object's mass by its volume. Examples of physical changes include melting, freezing, boiling, and condensing, which change a substance's state but do not form new substances.
Chapter 1 part ii
This document summarizes key concepts from Chapter 2 of a chemistry textbook, including:
1) Physical quantities like mass, volume, and temperature can be described using a number and standard unit, such as kilograms for mass.
2) The International System of Units (SI units) provides standard units for many physical quantities to avoid confusion.
3) Other concepts covered include density, specific heat, scientific notation, and methods for measuring or converting between different units.
Mass Volume Density
Mass is the amount of matter in an object, volume is the amount of space an object occupies, and density is the mass per unit volume of an object. Mass is measured in grams using a balance, volume is measured in liters or cubic centimeters by multiplying length, width, and height or using liquid displacement, and density is calculated by dividing an object's mass by its volume and expressed in grams per milliliter or grams per cubic centimeter. Volume can be measured through liquid displacement by placing an object in water and calculating the difference in water levels.
Errors and uncertainities net
- Random uncertainties arise from imprecision in measurements and can cause readings to be above or below the true value. They can be reduced by more precise instruments or repeating measurements.
- Systematic uncertainties result in all readings being consistently too high or too low. They may be due to instrumentation errors or experimental technique and can sometimes be addressed through calibration.
- Uncertainty is incorporated into measurements as a range rather than a single value, and it is important to propagate uncertainties through calculations.
Unit 1 notes_pp_12_13
Chemistry is the study of matter and the changes it undergoes. Matter has mass and takes up space, and can be either elements or compounds. Elements are pure substances made of one type of atom, while compounds contain two or more elements chemically bonded together. Properties of matter include physical properties that can be observed without changing its composition, and chemical properties that involve its reactivity. Energy is the ability to do work or cause change and can exist in different forms like kinetic, potential, chemical, and heat energy.

Ch10 outline
Gases are highly compressible and expand to fill their containers, with pressure inversely proportional to volume according to Boyle's Law. The properties and behavior of gases can be explained by the kinetic molecular theory, which models gases as large numbers of molecules in random motion. Real gases deviate from ideal gas behavior at high pressures and low temperatures due to intermolecular forces and molecular volumes.
Ch08 outline
There are three main types of chemical bonds: ionic, covalent, and metallic. Ionic bonds involve the electrostatic attraction between oppositely charged ions. Covalent bonds involve the sharing of electrons between atoms. Metallic bonds involve metal atoms bonded to several other metal atoms. The strength of bonds can be estimated from bond enthalpies, which measure the energy required to break chemical bonds. Bond strength increases as bond length decreases.
Ch07 outline

Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
