Scientific notation is a way to express very large or small numbers using two parts: 1) a number between 1 and 10 and 2) a power of 10. To convert a number to scientific notation, the decimal is placed so there is one non-zero digit left of the decimal and the number of places the decimal moved indicates the exponent of 10. Converting back involves moving the decimal right for positive exponents and left for negative exponents.

Scientific Notation
This document provides instruction on scientific notation and powers of 10. It begins with examples of evaluating and multiplying numbers by powers of 10 by moving the decimal point left or right. It then discusses writing numbers in terms of powers of 10 based on the number of places the decimal point is from 1. The document also covers converting between standard notation and scientific notation. It applies these concepts to astronomy examples of writing planet diameters and distances in standard and scientific notation. Finally, it discusses comparing and ordering numbers expressed in scientific notation.

Scientific notation is a way to write very large or small numbers as a product of a number between 1 and 10 and a power of 10. To convert a number to scientific notation, the decimal is moved to place one non-zero digit before the decimal point, and the number of places the decimal is moved determines the exponent of 10. Numbers greater than 1 have positive exponents, while numbers less than 1 have negative exponents. Converting back to standard form moves the decimal right for positive exponents and left for negative exponents by the value of the exponent.

This document discusses scientific notation and arithmetic operations using scientific notation. It begins by explaining the rules for writing numbers in scientific notation, including how to determine the coefficient and exponent when the number is very large or very small. It then provides examples of addition, subtraction, multiplication, and division of numbers in scientific notation, and explains how to perform operations when the exponents are not the same. The document is intended as a lesson for third year secondary physics students.

Unit 1 2 scientific notation
This document introduces scientific notation and provides examples for converting between standard and scientific notation. It explains that scientific notation uses a number and exponential term to represent very large or small numbers. Standard notation numbers are converted to scientific notation by moving the decimal point to the left or right until there is one non-zero digit before the decimal, and adjusting the exponential term accordingly. Calculations can then be performed using scientific notation on a calculator. The document provides examples and practice problems to illustrate these concepts.
Scientific notation
Scientific notation is a way to write very small or large numbers as a coefficient between 1 and 10 multiplied by a power of 10. The exponent is positive if the decimal is moved to the left, and negative if moved to the right. To convert a number to scientific notation, identify the place value of the decimal and use that number as the exponent in 10^n, where n is positive or negative depending on decimal direction.
PowerPoint_Ch2_Section2.1 and 2.2.pdf
1) Scientific notation is used to express very large or small numbers in a more compact form. It expresses numbers as the product of a number between 1 and 10 and a power of 10.
2) To convert a number to scientific notation, the decimal is moved to place the number between 1 and 10, and the power of 10 is determined by the number of places moved. Positive exponents indicate moving left, negative right.
3) When adding or subtracting numbers in scientific notation, they must first be converted to the same power of 10 before performing the operation. Multiplication and division directly apply the rules of adding or subtracting exponents.

Motion and vectors regents
1) Physics quantities can be scalars or vectors. Scalars have magnitude only, like distance or speed. Vectors have both magnitude and direction, like displacement.
2) Displacement is the vector between the starting and ending points of an object's motion. It can be less than the total distance traveled if the object does not move in a straight line.
3) Vectors are represented by arrows, with length for magnitude and angle for direction. Vector addition uses the parallelogram method or tip-to-tail method to find the resultant, or sum, vector.

Motion and vectors regents
The baseball was thrown at 90 mi/hr, not 90 m/s.
Let's solve this step-by-step:
1) Convert 90 mi/hr to m/s:
90 mi/hr = 40 m/s
2) Use the equation d = vt:
d = 18.3 m
v = 40 m/s
t = d/v
t = 18.3 m / 40 m/s
t = 0.46 s
You're right, my initial solution was incorrect. Thank you for catching my mistake! Let me re-work this properly.

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.

Scientific notation
- 1. Scientific Notation Scientific Notation is a way to express very large numbers or very small numbers
- 2. Scientific notation consists of two parts: • A number between 1 and 10 • A power of 10 N x 10 x
- 3. Changing standard form to scientific notation.
- 4. To change standard form to scientific notation… • Place the decimal point so that there is one non-zero digit to the left of the decimal point. • Count the number of decimal places the decimal point has “moved” from the original number. This will be the exponent on the 10.
- 5. Continued… • If the original number was less than 1, then the exponent is negative. If the original number was greater than 1, then the exponent is positive.
- 6. Example 1 • Given: 289,800,000 • Use: 2.898 (moved 8 places) • Answer: 2.898 x 108
- 7. Example 2 • Given: 0.000567 • Use: 5.67 (moved 4 places) • Answer: 5.67 x 10-4
- 8. The age of the universe is approximately 14,000,000,000 years How would you express this number in scientific notation? 1.4 x 1010
- 9. Changing scientific notation to standard form.
- 10. To change scientific notation to standard form… • Simply move the decimal point to the right for positive exponent 10. • Move the decimal point to the left for negative exponent 10. (Use zeros to fill in places.)
- 11. Example 3 • Given: 5.093 x 106 • Answer: 5,093,000 (moved 6 places to the right)
- 12. Example 4 • Given: 1.976 x 10-4 • Answer: 0.0001976 (moved 4 places to the left)
