Powers of 10

In order to write very large, or very small numbers efficiently, scientists use a system of writing in powers of 10. For example, the number 108 represents 10 multiplied by itself 8 times, which is a 1 with 8 zeroes after it: 100,000,000. Thus, rather than writing 300,000,000, a scientist will write 3 × 108. Similarly, a number like 10-21 represents 0.1 multiplied by itself 21 times, which is a 1 with 21 zeroes in front of it (including the one before the decimal point): 0.000000000000000000001.

Four Areas of Science


Go, wond'rous creature!
Mount where Science guides,
Go, measure earth, weigh air,
    and state the tides;
Instruct the planets in
    what orbs to run,
Correct old Time,
    and regulate the Sun.

About SXS

The SXS project is a collaborative research effort involving multiple institutions. Our goal is the simulation of black holes and other extreme spacetimes to gain a better understanding of Relativity, and the physics of exotic objects in the distant cosmos.

The SXS project is supported by Canada Research Chairs, CFI, CIfAR, Compute Canada, Max Planck Society, NASA, NSERC, the NSF, Ontario MEDI, the Sherman Fairchild Foundation, and XSEDE.
