Remember a 9mm is really only effective out to about 50 yards before it has slowed down enough that most of lethality is lost.
Complete and utter bullshit.
You might want to recheck that. The average nuclear warhead in the US arsenal is approximated to be 33,500 kilotons (slightly larger than the well known B41). For comparison, the nukes used in/on Japan were 15 and 21 kilotons. 33,500 kilotons is large enough to destroy/kill everything in a 55-60 mile diameter. It would take about 1000 of these to DIRECTLY kill everything in the United States. Factor in the indirect damage (nuclear poisoning, fallout, etc etc), and you could kill everyone in the United States with far far fewer. India (for example only), has 1/3rd the area of the United States. It would take probably 100 33.5 megaton nuclear bombs to kill everyone in an area equal to the size of India, and it would likely kill a couple hundred million of people not in that area.
That's completely false, most modern missile-based nukes are in the hundreds of kilotons, like 100-500 kt. 33.5 megatons is larger than the largest bomb we've ever had in service, the B53 at 9 megatons.
I've heard numerous variations of this by parents trying to justify why their precious snowflake doesn't do well in school. Usually it is the teacher's fault, and their child is just so much smarter than the other students. BS. If your child is so super intelligent that ordinary schoolwork bores them, they should be smart enough to breeze through the tests. They should just "play the game" while at school and do their own learning at home, or in additional enrichment programs (most are free for low income).
You aren't allowed to just breeze through the tests. You are also required to do hours and hours of repetitive, mind-numbing homework that is below your level and serves no useful purpose if you're smart enough to just listen to the lecture and then ace the test. If you don't do the busy-work, you receive a failing grade regardless of how well you do on the tests.
Most use stereo because we have 2 ears... and therefore only 2 channels are necessary for 3D sound. 5.1 is a gimmick. Stereo forever.
That's false. We only have 2 ears, but each of those ears can distinguish sound coming from many different directions because your head and earlobes alter the sound differently depending on where it comes from. You can only try to generate realistic soundfields with 2 channels if you use headphones. You can record sounds with microphones in the ears of a dummy head (binaural recording), or you can try to simulate these effects through headphones. Both of those methods have problems, including the fact that the sound stays the same when you turn your head.
By your reasoning, we should only need 2 pixels on a TV since we only have 2 eyes.
I have a theory that it's impossible to prove anything, but I can't prove it.
