Re: Stupid question of the day

Apropos the Dirac delta and speed of whatever, what does it mean to accelerate the relationship?

And not anyone had second thoughts about camping on a site when they were about to install an electric fence against polar bears...

So, my stupid question of the day is: speed of what?

Re: norway

Ukrainian and Polish have lots of words for rain. I particularly like "kapuśniaczek" (lit. the diminutive of cabbage soup), which means a small rain. In Ukraine we had small fleeting rains which came locally out of nowhere on a sunny day and passed almost unnoticed - we called them Курячий дощ (chic...

Re: norway

Thanks! I suspect a true Norwegian would reduce it to "litt overskyet" :-)

Re: norway

Det er kraftig regn.
My Indo-Euro guess 'it rains heavily'?

It's all about the rain in Galway!

It's heavy rain, exactly. Det var ganske fint i dag, men det dukket jo opp litt skyer her og der pa himmelen.

Re: Stupid question of the day

It's a kind of question for which one knows or does not know the answer at a glance. Not really. To begin with - and following Alan's thoughts - depending on whether your model is continuous or discrete, you'd use Dirac or Kronecker delta, respectively. The distribution form is not wrong but it def...

Re: Stupid question of the day

I think the maths stays the same as in Alan's answer. For higher order impulses think of a gaussian and its consecutive derivatives, and then imagine what happens as sigma goes to 0. It's too enigmatic, typically of your questions. We don't know the context. Does your task have something to do with ...

Re: Is it over?

"However how can it be standard physics have given Hawkings exemptions for the 4th law of thermodynamics?" Because Hawking's black hole "temperature" has nothing to do with the thermodynamic temperature as we know it. You can test it by bending the timespace near your window thermometer (careful not...
