Re: Squares

I don't have an FCC license , you have to be proficient in Morse code , and i had difficulty learning Morse code...So i didn't get the license.. All Morse code was dumped from the Ham licence in the USA back in early 2007. I only took "General Math" in high school , i didn't take algebra ...

Re: Squares

@Albert. It is now long past the time that you should have stopped expecting to stumble upon a herd of Unicorns, while looking at patterns in numbers and formulas. Most 12 year old school students understand that there is a field of mathematics called algebra. They know that algebra makes it possibl...

Re: Squares

@ Albert. n = int( rnd * 6553 5 ) mod 256 n = Int( Rnd * 6553 6 ); generates random 16 bit Uintegers from 0 to 6553 5 . x = n Mod 256; keeps only the 8 bits on the right and throws away the most significant 8 bits. Those missing bits are y = n \ 256, they cannot be recovered. LoByte(n) and HiByte(n)...

Re: Squares

Note: If the question is not very understandable or changing, we can hardly help. You guys; I'm trying to round the 16 bit input ( 0 to 65535) to 1 or 2 decimal digits , and then try to recreate the input with just those 2 digit places. No one can possibly help if it is both mathematically impossib...

Re: Squares

What are you trying to do.

Re: Squares

@Albert. YOU are WRONG.
You have not realised the differences between forces, torques or energy.
Force * distance inline = energy.
Force * distance sideways= torque.

The metre was defined by the speed of light long ago.
Speed of light is exactly = 299,792,458.000 metres per second.

Re: Squares

If a spherical droplet of water falls on a flat lake, and no one is there to hear it, does it make a noise?

Re: Squares

I think the formula for water collision , energy. Is E = mass * drag *velocity ^ 2 Unfortunately Albert, all the terms you are using have been defined differently earlier. kinetic energy; KE = ½ * mass * velocity^2. That must be the case. The derivative of kinetic energy is momentum, p = mass*veloc...

Re: Squares

Two hours past the winter solstice here, and it is 0°C. But the sky above is –27°C which explains why the wallabies have eaten their mid-winter feast of apples and moved in under the shed to await sunrise and the melting of the frost. How then , does a pebble cause a wave? The mathematics is determi...

Re: Squares

@Albert. You describe things happening that seem more imaginative than observational.
It does not happen like that on planet Earth. What planet are you on ?

He did not write "do nothing to the reflectivity of water..". He wrote; "This appearance Will not be affected by even a slight motion of the air, and a velocity of less than half a mile an hour (8½ in. per sec.) does not sensibly disturb the smoothness of the reflecting surface". ...

Get a copy of capture2text, then you can ocr text from images on your screen. Let him begin his observations in a perfect calm, when the surface of the water is smooth, and reflects like a mirror the images of surrounding objects. This appearance Will not be affected by even a slight motion of the ai...

Re: Squares

Albert wrote:John Scott Russel's book: says it takes at least a 1 mph wind to disturb the water surface.. ( cause ripples )
I do not believe that is a true quote.
When you quote from a book you must give a page number reference so any reader can check the context.

Re: Squares

Not only must the two sides of an equation be numerically equal, but the equation must also have the same units and dimensions on both sides. Acceleration * Volume = displacement per second; Displacement has dimension of length. Volume has dimensions of length * length * length . Acceleration has di...
