I don't believe that claim at all, and I'm too tired to check the source. Reason why I don't believe it, is that it would make for an excellent biomarker for autism, as today we have none but instead make potential autists go through psychological screening in order to diagnose.

Amazon is EXTREMELY dumb about space and has fully drank the MARS MAN BAD koolaid. AWS Ground Station was the one good spess idea they ever had but the implementation is ass because if you need data from the other side of the planet to be brought back to your country for processing you eat those inter region transfer fees... so it's probably cheaper to just build your own ground station or beg time on the DSN.

I'm in the process of learning probability and statistics, but I simply cannot force myself to go through these abstract books. Has anyone read any books they can recommend on gambling ("applied probability and statistics") -- or anything of that sort -- that puts all the math into a real-word context?

And to add to that, look at what SpaceX charges the government, versus other companies. For example, for the commercial capsule program NASA paid SpaceX about 2/3rds of what Boeing has received. And for that, SpaceX has delivered a working product with its Dragon capsule, while Boeing's Starliner fucked up on the unmanned test launch in 2019, and has not been to space since.
Or look at the Air Force and GPS launches; SpaceX charges them about half the price ULA does. Complaining about someone selling services to the government, when they are by far the cheapest bidder, is dumb.

I practice bouncing off whatever main and secondary points I want to make and layout the order of it all. A word for word script sounds a bit odd but I'm not someone who gives presentations often or particularly well.

It's done, I did this the day before. Tons of anxiety when it came time but I was calm throughout the presentation. I didn't like the feeling prior to it though. I think it's something to work on in future.
>>14365690
It was in person and a few questions.
>>14366588
Some people had scripts but I was ok without one, I just read partially of the slides and used own knowledge. It helps that I did some public speaking (debate) for around 3-4 years.

Don't read from a script, don't memorize a script, know what is coming next in the slides and any bullet points to cover should be on the slides. Any additional information you should already know

good presentations are a combination of both rehearsed key points and off-the-cuff supplementation

the danger of over-scripting your presentation is that when some faggot walking by your poster or sitting in the front row at your talk who ambushes you with a smug gotcha question you're not prepared to go 'off book'

Two Functions Same Axis of Symmetry Same Roots

Anonymous Tue 05 Apr 15:22:39 2022 No.14366505 View Reply Original Report

Quoted By: >>14366523 >>14366586

How come the second function shares the same roots and axis of symmetry after I factored out -1/5 from the first function, yet has a completely different graph other than where the roots meet? Of course, if I divide or multiple all the terms of a polynomial, the graph will be different, but why are the roots and the axis of symmetry preserved under polynomial multiplication and division by a constant?

Absolutely, especially when you have to handle the passage of hydraulic fluid through orifices and servo valves in order to reach the piston which moves the surface. Lots of tests are run where we increase the size by a minuscule % and see how everything changes.
