The second has an uncertainty attached. C defined as exactly 299,792,458 m/s is an abstraction. It can not be exactly demonstrated. The numerical value can be anything depending on the system. In a system based on a sand clock and furlongs C would be defined as furlongs/grains of sand. The...

Love is about mutual feelings. A hammer cannot feel your love, although you may feel your hammer loves you back. No one claims science is infallible or omniscient seeing all ends or is able to understand and explain all things. That would be the purview of the Christian god. If you put it in...

If I were to be formal and exact I would include the published uncertainties of the second, and kilometer, and speed of light. It is neither 24 nor 39 million. Just sayin'. For routine calculations 300,00 km/s for C is used.

Lion All cultures having myths of one kind or another. That there are many god myths does not prove any god exists. Do you believe physical illness is caused by bad spirits that can be let out by drilling a hole in the skull, as some people once believed? Or do you go by modern medical...

Ok Lion... How about monkeys with an infinite amount of time writing random thoughts that end up as a myth that monkeys believe? IOW wandering ancient nomadic camel jockeys thinking up a creator-god? That all cultures had and have myths obviously say there is no unique 'true' god or gods...

For nonvolatile program code memory there was EPROM. A programmable memory chip erased by UV light through a window in the chip. https://en.wikipedia.org/wiki/EPROM Then came EEPROM electrically erasable programmable read only memory. A big deal in the day. You could remotely change code in...

Where do you derive this from, other than your imagination? Where in the gospels does JC put aside his Jewish faith? You are confuting the gospel Jesus with Paul. Jesus reinforced Mosaic Law, Paul despised with it. Circumcise does not make a Jew Jewish....paraphrasing. OMG!! Now ot is about...

Like most Christians you ignore the question. For 2000 years what have been the consequences of this movement? Jews, Muslims and Christians ostensibly have the same god. Yet there is conflict between the three faiths and conflict within each faith. Jews, Christians, and Muslims emancipation...

And for 2000 years what has been the overall results of that movement? Be specific if you can, no generalities.

A good basic technical calculus book. https://students.aiu.edu/submissions/profiles/resources/onlineBook/x2Y3u2_basic%20technical%20mathematics.pdf

Watched an old movie about Custer with Errol Flynn as Custer. Given what we know historically of Custer the movie was essentially horse shit. It paints Custer as compassionate and sympathetic to the 'Injuns' instead of the genocidal man on a mission he was. I visited the battlefield on a cross...

Beyond straightforward textbook kinds of problems I always used numeral integration. and differentiation. n = 1000 y = np.ndarray(shape=(n),dtype=np.double) derv = np.ndarray(shape=(n),dtype=np.double) integ = np.ndarray(shape=,dtype=np.double) t = np.linspace(0,2*np.pi,b) dt = t[1]-t[0] for...

And the transform of step function is sin(x)/x n = 1000 y = np.ndarray(shape=(n),dtype = np.double) t = np.linspace(0,20*np.pi,n) #radians for i in range(n):y[i] = np.sin(t[i])/t[i] y = abs(y) plotxy(0,max(t),-1,1,t,y,"","","")

I would never discourage anyone's interest in math, The math and science forums once lively have been dead for a while. Post away.

Jaryn I know next to nothing on number theory but I know something about step functions and transforms. Se the post on the FFT thread, you can see the transform for yourself.
