Good question.
I think that the greatest contribution of QM to the engineering has been the electronic devices.For example,earlier we had mechanical governers in the automobiles while now we have electronic sensors and actuators doing the same job at comparibly very high accuracy and with low...

It's my first time here,and I want to get some help.
My sub is condensed matter,and now I am doing some experiments on superconductor.What confuse me greatly is...
another(?) way is to just use the substitution x=0 again and again as follows:
if p(x)= ax^n + bx^(n-1)...+ z= 0 for all x
then @ x=0
p(0)=0 => z=0
then take x common and write
x(ax^(n-1) + bx^(n-2)...+ y) = 0
(y is the coefficient of x in p(x))
since this is of the form...
thanks for the inetresting article.
But I am wondering whether this applies to excitation by EM waves.
Consider this and don't shy from bullying me if i am wrong :wink: :
The article says that the smell is a function of vibrational spectra and not structure but this vibration spectra...
'feel' means percievable by one out of our five senses.
smelling EM waves is certainly out because the olfactory sensors usually respond to only things that have mass.
tasting EM waves is also out for similar reasons
hearing them is out because the pressure fluctuations they generate...
As for the fly question,I think its just the viscous force which accelerated it forward when bus strated again.When the bus is not moving, the air inside is also stationary and thus fly experience no viscous force.When the bus starts moving,the air inside the bus can be seen as a stream (or...
Interesting Quantum Mechanics Problem
Suppose we have a particle in a box with infinite potential for x>a and x<0 and zero potential in between.Then by solving the schrd. equation we get a node at x= a/2 for first excited state.Which means the probability of finding the particle at x=a/2 is...
a= -w.w.y
'-' sign is there because here 'a' is component of acceleration in the radial direction which is normally taken positive outwards.As the centripetal acceleration is towards the center its component along radial direction is negative,hence the negative sign ('w' and 'y' are positive...
please read it through,it will help:
both dv/dx and du/dy are along the same direcdtion viz the z-direction.in other words,what we are doing is measuring how much the body's vertex angles have changed from initial 90 degrees.in many books i have seen a subscript 'z' instead of 'xy' with the...
if you practice 'yoga' you will certainly sharpen your senses.it can't be explained in words(atleast i can't do), you have to experience it.
certainly its cool
