So, I learned in physics class at school in the UK that the value of acceleration due to gravity is a constant called g and that it was 9.81m/s^2. I knew that this value is not a true constant as it is affected by terrain and location. However I didn’t know that it can be so significantly different as to be 9.776 m/s^2 in...
Interesting that I learned 32.2 ft/s, but only 9.8 m/s - one less significant figure, but only a factor of two in precision (32.2 vs 32 = .6%; 9.81 vs 9.8 is only 0.1%). Here's the fun part - as a practicing engineer for three decades, both in aerospace and in industry, it's exceedingly rare that precision of 0.1% will lead to a better result. Now, people doing physics and high-accuracy detection based on physical parameters really do use that kind of precision and it matters. But for almost every physical object and mechanism in ordinary life, refining to better than 1% is almost always wasted effort.
Being off by 10/9.81x is usually less than the amount that non-modeled conditions will affect the design of a component. Thermal changes, bolt tensions, humidity, temperature, material imperfections, and input variance all conspire to invalidate my careful calculations. Finding the answer to 4 decimal places is nice, but being about to get an answer within 5% or so in your head, quickly, and on site where a solution is needed quickly makes you look like a genius.
It would seem logical that Trump would want to demonstrate - once and for all in a court of law - that he is innocent of any wrongdoing as soon as possible so as to not have it hanging over him in the race. Mr. Smith is merely offering him that opportunity.

Yeah, with what majority? There are only 47 Democrats and 2 independents who are interested in any politics left of center. Manchin, techincally a Democrat, will only vote for his personal, center-right beliefs, and Sinema, the only remaining independent has shown she's in it solely for personal financial gain. There was no time in which there were enough Democrats, excepting the two aforementioned posers, to add seats to the court or confirm any justice without some money changing hands. If it weren't about power or money we could have had 52 states (DC and PR) and at least 3 more truly democratic senators (considering the outside chance of a 50/50 split in PR). But that was impossible because it would have reduced the power of Manchin and Sinema, and that's the only reason for them to exist.
Does everyone learn the same gravity in school or is it different everywhere?
