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.

Code: Select all

 print " >>> "; Cint( 2.56 * Int( v1 / 2.56 )  )

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 ?

Re: Squares

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". ...

Re: Squares

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...

Re: Squares

Different objects have different flexibility.. If you flex and object passed it's maximum flexibility, it will break. Correct. That is shown in the stress strain diagram used by engineers to determine the strength of materials. That diagram also shows that deflection = strain, is directly proportio...

Re: Squares

Read the book carefully.
Page 73 explains that waves are the same even when initiated by different causes.
Russell was first to describe the tidal wave phenomenon. He classified it as a “solitary wave”. They are now called “solitons”. https://en.wikipedia.org/wiki/Soliton
