There are likely millions of primes between this one and the previous largest number...There's a decent chance we'll never find one.

There isn't really. Large primes are used for encryption but numbers this large are useless there (for now, at least). In reality much of the search is just math for math's sake. A lot of basic research is like that, to answer questions nobody else has or currently cares about. Some becomes...

If you really are an Aerospace Engineer you would know the main variable in sonic boom intensity is the quantity of air being accelerated, therefore the main driver(s) of a strong sonic boom is aircraft size and shape. You would also know that beyond about 1.3-1.4 speed is almost an irrelevant...

There are have been munitions with cockpit selectable PRFs for a looooooooong time. Most new laser guided munitions have such a feature by default. As someone else said, this is due to the lack of interface with the pod.

Manually dialed PRF selectors? WTF? What is this the stone age?

If what you're doing only requires textual input, sure. Too bad for this guy computing has expanded it's role and interface requirements. I've had to work with ancient government computer generated hardware models that only used keyboard navigation.... so much so the keystrokes are second...

Malfunctions are fairly common in the middle of a firefight, ask anyone in the military who's actually been in a few. You take cover, clear your weapon, and move on. No firearm works 100% of the time. NONE.

There are an embarrassing amount of people in America that do not think fossil fuels will ever run out. This also applies to a surprising number in congress.

c'mon now....it's not a mustang :D

He's doing it for clicks. Dude just bought a new Model X (notice he also says on twitter they've gone through 3 sets of tires in 2 years with the Model S...so he clearly knows to change tires). My guess is he roasted the tires knowing he was getting rid of the car. Hell, I do so whenever I'm...

There was a mild recession in the early 90's, the Aerospace industry is susceptible to such things like everyone else. Nowadays we can't find enough talent. My own company has a goal of hiring 2000 more engineers this year (obviously not all are entry level spots) and we are on track to hit...

Mohonri is correct. I don't know of any EEs that have dedicated courses for statics, machine mechanics, dynamics, thermo, or fluids. It's not needed. Also in my experience the aerospace industry is fairly stable as far as engineering employment. If you work in defense, a program might get...

Valid points as well. Though my point about certain fields of engineering not needing a PE to be called an engineer still stands. Example: In my field a PE is almost worthless outside of VERY few niche positions. However, an FAA DER (Designated Engineering Representative) is FAR more...

Oh jesus christ. You are the kind of PE that makes the rest of us look bad you pretentious prick. Some overly broad statements you are making here. First of all, a PE is only relevant in a few fields of engineering. Civil, HVAC, Nuclear, and EE's working in power come to mind. Most ME's don't...

To be fair, none of these things MAKE you an engineer either. I know many wannabe AEs that knew all the basics like this but were incapable of abstract thinking. They didn't last long in the aerospace industry.
