Is there an explanation for why the speed of light tops out at 186,282 miles per second? Of course that number depends on our definition of miles and seconds. If a mile was 3000 feet then c would be a different number. But whatever speed it is…. Why that speed? In other words… there is...

I understand that it’s an absurd hypothetical. My curiosity is, I admit, due to my ignorance. But the equation which I thought was correct…ke=1/2mV^2…seemed to accept any value for V, whether 100mph or 400000000 miles per second (well over c), without regard of the impossibility of exceeding...

Kinetic energy = 1/2 m V^2 I was thinking about this and thought another formula… E = mc^2 These look very similar except for the multiplication by 1/2. Let’s say you take a kilogram ball of uranium and accelerate it to the speed of light. I know, I know. You can’t. But let’s say you did...

But, my conjecture is this…if someone DID find an even prime, there would have to be an infinite number of them. Tex

I think that’s my point. If indeed, by this conjecture, there must always be an infinite number of members of a set of any series which is based or dependent on, or draws from the infinite set of numbers, then trying to prove a series is infinite is pointless. We can know that it must be...

Any set of a series of numbers consisting of increasing integer members, all of which are determined by a common proposition or characteristic, will always be infinite in size. Examples… Prime numbers Mersenne primes Odd perfect numbers(if they exist) Zeroes of the Zeta function Regardless...

I think I have discovered why some people here have been confused about the curve. There IS slippage! The aircraft will make a circle defined by a constant rate of 3 degrees per second at its velocity, say 120 kts. The wind will blow at some random speed. Any wind speed produces some form...

In a recent thread, I thought I understood what was going on but alas, I am still confused. So I offer this diagram and ask for more help please. Shown is an aircraft holding pattern. The one on the left is flown in still air. The one on the right is flown with a wind coming from the...

Here is the curve in question. The center of the "wheel" travels along a straight path. The height of the curve is equal to the radius of the circle. The length of the curve is determined by the distance between the starting point of the curve (let's call it the 270 degree point on the...

I see two curves here. One, the result of turning and flying with the wind (the yellow) and the other when turning and flying into the wind (green). Here are a couple of questions... 1. Are these two of the same kind of curve (for example, cycloid, if that is indeed what it is, or whatever)...

What would be the name of the type of curve created? Is it a cycloid, curtate cycloid, prolate cycloid or epicycloid. I ask because there are many good youtubes on how to create these in autocad. tex

First, I understand how wind effects aircraft tracking. I can do the calculations involving wind correction angles, effects on ground speed, headwind or tailwind calculations, etc. I teach it in a college piloting program. I am wondering how the ground tract of turn is effected by the wind...

This has bothered me for quite some time. This drawing represents the plastic ring around your typical 6-pack of Dr. Peppers, Coke or most any 6 pack of something. The ring consists of 6 loops for the drinks, two small internal loops, and one handle loop. As any good dolphin lover would do...

Please explain how we know that it is space itself that is expanding rather than an expansion due to an explosion such as the big bang. In either case wouldn’t every object appear to be moving away from us? How do we determine that space/ time is expanding? Tex

My interest is in whether there is enough info in the video from the explosion to determine is size. If a forensic scientist tried to determine the size of the boat just using the explosion could he, knowing nothing else? Tex
