    Largest Prime Number to Date Discovered

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

    Largest Prime Number to Date Discovered

    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...

    Boeing Unveils “Son of Blackbird” Hypersonic Spy Plane Concept

    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...

    APKWS or Advanced Precision Kill Weapon System - OOORAH!

    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.

    APKWS or Advanced Precision Kill Weapon System - OOORAH!

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

    Almost Everything on Computers Is Perceptually Slower Than It Was in 1983

    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...

    Hacker Unlocks “Secure” Smart Gun with $15 Magnets

    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.

    Tesla Owner too Stupid to Buy New Tires

    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.

    Tesla Owner too Stupid to Buy New Tires

    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...

    Oregon Man Temporarily Wins the Right to Call Himself an "Engineer"

    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...

    Oregon Man Temporarily Wins the Right to Call Himself an "Engineer"

    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...

    Oregon Man Temporarily Wins the Right to Call Himself an "Engineer"

    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...

    Man Fined $500 for Writing "I Am an Engineer" in Email to Oregon Engineering Board

    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...

    Oregon Man Temporarily Wins the Right to Call Himself an "Engineer"

    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.
