### Re: Could Neutrinos be Gravitons?

I'll tack this on the end...

The fact that neutrinos likely have mass is important because gravitational waves can be shown to travel at something close to the speed of light.

### Re: Physics and the essential math behind it <- question

Study what you can formally, and study the rest informally. Knowledge of mathematics is possibly the most valuable thing to anyone ever anywhere.

### Re: Are smashed particles 1-2 dimensional objects?

Nobody really has a compelling answer. But the standard model, as mentioned above, models them as zero dimensional particles. It's just a model. How many dimensions does a light wave have in a moment in time? None. Kind of intuitive, but still just a model.

### Re: Integration Algorithm

What about using something like Simpson's rule to approximate a function really well?

Then you would at least have a systematic way of calculating the integrals if you know the function, and to a pretty good degree of accuracy.

### Re: Tunnel to earth's core with molten iron?

I think a probe would only be icing on the cake. It'd just be fun to make a giant hole.

Though it is nice to see a potential in researching electronics at high temperatures. Largely untapped areas like that dilate my pupils.

### Re: "Special" four digit number

This reminds me of how Richard Feynmann opened those safes during the Manhattan Project. I think he did it by using the first n digits of e. But that'd probably too cliched or obvious. That 'special number' list is special, though.

### Re: Seemingly ridiculous rules/conventions

I agree with current = I and imaginary unit = i. I have certainly seen j used for current, though, but I don't know what took i's place in those cases. Electrical engineers are just queer. I reckon I kind find a use for quaternions in some sort of something, then it'd really mess things up notation ...

### Re: Seemingly ridiculous rules/conventions

This isn't so ridiculous, but: I think it is kinda cute with your electrical engineers using 'j' for the imaginary unit when using 'i' for current. But that alone isn't ridiculous. I'm wondering what happens when j is used for current. Is the imaginary unit then denoted by the letter 'k'? Funny if i...

### Re: Logistics of large state diagrams.

Thank you.

Unfortunately a state diagram is a requirement. I find they, like Karnaugh maps, become less useful as things get bigger. I'm only first year university, and not even studying computer science, so hopefully I won't deal with too much of this stuff.

### Logistics of large state diagrams.

Ahoy,
I'm making a state diagram for an alarm clock (school related) and I need 60 states for the minutes machine.

How do you neatly pack 60 states into a state diagram? Is there an accepted shortcut?

It kind of looks like a long snake at the moment.

Thank you, computernauts.

There is a probability that the floor could vibrate in such a way to bounce the ball exactly that way.
There are no laws being broken.
It violates conservation of energy as much as a game of basketball does.

I'd bypass the the mic altogether. An easy solution would be taking the 1/4" jack from the speaker output and plugging that into the pedalboard or what have you. You'd probably want to use a DI in between them, but I usually live dangerously and just have it on low volume so I don't kill whatev...
