  1. Don't you think the term "academic" is rather too vague. It could encompass all persons who have attended an institute of learning. Whatever the learning was about. Thus, a Professor of English Literature, and a Professor of Nuclear Physics, could both be described, simplistically, as "academics". That's to say, they've learned things that most people don't know about. But the distinction between them is this: The Physics professor gets his knowledge from following new experiments in modern science. Whereas the Literature professor gets it only by studying old books. Therefore, I would classify the Literary bloke as a "Scholar". Not a "Scientist" at all. Even though he's an "Academic". Isn't there a huge difference between being a "Scholar", and being a "Scientist"?
  2. Could you translate your program into BASIC, please, as that's the only programming language I understand?
  3. Just wondering why water should impede radio-waves. Water is composed of Hydrogen and Oxygen. Neither of these two elements, by themselves, seem to offer much resistance to radio-waves. For example, the Oxygen in the Earth's atmosphere doesn't prevent terrestrial radio stations from receiving broadcasts over long distances. And Hydrogen gas, which is present in large quantities on the planet Jupiter, doesn't prevent random radio-noise from that planet, being received over even longer distances by our radio-telescopes on Earth. This demonstrates that both elements are transparent to radio-waves. So why do Oxygen and Hydrogen when combined together in the form of water, block radio waves so strongly?
  4. Haven't Eddington's so-called "photographic" proofs of star-displacements caused by Einsteinian effects, long been called into question and discredited?
  5. Uhm. When you say "fairly reproducible results"... "with uncertainties", does that sound like Science in its true sense? I mean, couldn't Scientists such as Physicists and Chemists, provide exact answers to questions?
  6. Do you think that a "Sociologist" is really a scientist, in the same sense that a "Physicist" or "Chemist" is?
  7. Yes, but haven't theoretical physicists developed models such as "String Theory". A theory which apparently cannot be tested by any practical experiments. If so, is "String Theory" science? Or just philosophical speculation.
  8. But theoretical scientists only write mathematical equations on paper. They don't do any physical experiments, to see if what they write actually works in the real world.
  9. Isn't a "scientist" someone who has an urge to do experiments?
  10. Navigation of the supersonic sub will also present difficulties to the captain. Travelling sub-surface at a dash-speed of 850+ mph, he/she will be essentially operating blind. Sonar will be of little help - aquatic shock-wave effects will delay and distort echo-returns from enemy vessels. Thus rendering precise torpedo launches hopeless. Probably, the best military tactic for the supersonic sub, will be to come up to periscope-depth near an enemy ship, and get a directional bearing through the scope,. Then submerge, accelerate up to supersonic speed, and execute a ramming attack - Jules Verne "Nautilus" style - to slice the bottom off the enemy vessel by sheer kinetic energy. This will not damage the super sub, as its hull will, of course, be built of titanium/depleted-uranium alloy. What could possibly go wrong?
  11. Swansont, after pondering about the interesting point you mentioned, "shock waves in water", I've come to the conclusion that supersonic submarines can't be compared to supersonic aircraft. For this reason: Aircraft fly through the Earth's atmosphere - ie, through a mixture of gasses. And gasses can be readily compressed, and pushed aside. Thus generating a Mach "shock-wave" in the atmosphere. The atmosphere absorbs and dissipates the shockwave, turning it into a "sonic-boom". Which may annoy remote ground-based residents. But doesn't molest the aircraft. However - water is a different matter. Water absolutely cannot be compressed. It retains its volume no matter how much it's squeezed. This is indeed, why hydraulic machines work. Therefore, it seems to me, that if a submarine accelerated underwater at ultra-high speed, then when it reached under-water Mach -1, the outcome would be crushing disaster for the sub. Can you fault my reasoning?
  12. Aircraft can be designed to travel at "supersonic" speeds through the atmosphere. Would it be possible to design a "supersonic" submarine to travel though the sea?
  13. Perhaps we are in the age of communication - when all humans can communicate with each other, for the first time.
  14. Do you mean that a change in velocity, by slowing down, is actually an acceleration?
  15. Thanks Bufofrog, I did make a reply, but it was deleted by a moderator
