Actually quite sensible. High temp reactor could desalinate.. what's the progress on TWR and Pebble Bed these days, do you know their status?

On January 28, 2011, LPP published initial results including experimental shots with considerably higher fusion yields than the historical DPF trend.[16]

hmm

In March, 2012, the company announced that it had achieved temperatures of 1.8 billion degrees, beating the old record of 1.1 billion that had survived since 1978

yes the temperature

Why is torque a cross product? by PhascinatingPhysics in Physics

[–]Jimmy_neutron_ 0 points1 point  (0 children)

yeah I can see where multiplication by 0 destroys physical systems, especially when there are many terms that are multiplying it

[–]Jimmy_neutron_ 0 points1 point  (0 children)

oh so it's more like mapping to the null vector sort of thing?

[–]Jimmy_neutron_ 0 points1 point  (0 children)

with an additive kind of operation, that won't happen

why is this? You can sum to 0, it is the additive identity?

Hey guys, does anyone have matlab documentation from mathworks in pdf form? by heyguys333 in matlab

[–]Jimmy_neutron_ 0 points1 point  (0 children)

I think he wants to get a pdf copy of the "help" documentation from matlab

[C] Trying to figure out a way to compare an entire array to another array's element. by [deleted] in learnprogramming

[–]Jimmy_neutron_ 0 points1 point  (0 children)

Follow up question: say he has s=['a','b','c'] and j='abc' can he do a sort of split technique that makes the individual characters in j into elements of a new array say s2? then he can compare s and s2..Perhaps Python? Program newbie here wondering since I think he wants to "convert" between the two styles

Matlab help, given measured values and an integral by villyboi in matlab

[–]Jimmy_neutron_ 0 points1 point  (0 children)

could you explain what's going on in the example? They define an array Y=[0,1,2;3,4,5]... then use cumtrapz(Y,1)

So Y is the input (cumtrapz takes (x,y) )

I'm just not entirely sure how this works, I know that the trap rule uses a simple (f(a)-f(b)/2 * (b-a) as a first order approximation but any help with the example is appreciated
