# Catalyst discovery
How are catalysts for chemical reactions found?
Given a hoped for reaction, let's take the hydrogenation of carbon monoxide to methanol as an example, do chemists:

Learning Outcomes
1. Interpret the y-intercept of a line as the value of y when x equals to 0.
2. Determine whether the y-intercept is useful for interpreting the relationship between x and y
Just like the slope of a line, many algebra classes go over the y-intercept of a lin... | {} |

# A Boost in Precision for Optical Atomic Clocks
Physics 11, 22
Researchers set a new record in atomic clock precision by using spectroscopic imaging to reduce frequency variations in a strontium optical lattice clock.
Today’s most precise atomic clocks are based on strontium, ytterbium, and other alkaline... | {} |

Before I got the gauge rod set,I used a starett small hole gauge to measure.
I recommend a headspace go guage for accuracy. If you don't have either the small hole gauge or rod set, you could use nice drill rear shanks to get one tight and then use a micrometer to measure. Start with a loose one and wiggle front and ba... | {} |
