To me, it is a mystery who invented and perfected theses basic shapes. One seemingly convincing answer I received is for circle is conceived from moon and triangle from mountain.. i do not agree for the later. If we observe the nature closely, the angles does not exists, the shapes are dominated by closer loops of curves. This is true. We have never seen "a suqare shaped animal or plant". Angular structures could be seen in microstructure of mineral lettices etc... but this is a recent contribution of microscopy.

Hello my name is Rob and I am working with matrices.



I am having a problem when it comes to fractions in matrices such as:



-25 -3 | -13

10 1 | 6



This is what I have done so far:



-1/25 * R1 è R1 which gives me:



-1/25 * -25 = 1 and -1/25 * -3 = 3/25 but know here is where I get messed up: -1/25 * -13 = 13/25 I know the answer is 41/25 but how did my book get 41/25





Please help, I am in need of fraction help!

I am seperating my proteins using microcentrifuge(Max.volume 1.5ml). I wonder what volume of sample should actually be put at maximum. because I remember someone saying that it should be two third of the max. volume, which is 1ml in this case. But now I need to centrifuge 1.5ml of my sample and want to know if its OK.
I want to avoid to seperate it into 2X0.75ml if possible due to the amount of work. There are no other type of centrifuges or rotors are currently available in this lab. And also, if anyone can explain why we should not centrifuge using max. volume( if this statement is true)? Sorry if this question is too basic. I am looking forward to hearing from you.

I am a bit confused about the exact nature of electric current flow.

Is electric current due to excess of electrons on the negative terminal of the cell/battery and these electrons leave terminal, flow through the conducting wire, reach the positive terminal (where there is electrons deficiency) of the cell/battery and and fill the gap

OR

The Cell, due to the electric field, sets up the conducting wire's electrons (not the ones in the chemical of the cell) move with a slow drift speed while electrical energy travels at the speed of light? or could it be viewed both ways?

I would appreciate a very clear detailed answer for this question kinnda bothers me a lot.

I am selling tickets to a game, wherein I toss a coin. If it's heads, I give u one rupee; tails, the game stops. The game can have infinite chances, provided heads keep coming. What will u be willing to pay for a ticket, or what should be the fair value of a ticket?
Have wracked my brains but just can't seem to get this one!
