Hey how can we make peltier tiles or plates at home with some less costing materials. Please explain with pictures. Thanks in advance!

This bladeless windmill works by movement of the pole due to the wind, then it is supposed to be flexible. What do you think is the material it will be made of? Secondly by the picture from the site we can know that it has less surface area, so the velocity of wind must be really high to make...

Then what else is the structure that an atom can have other than a sphere?

It is usually said that molecules are spherical in shape, that is what we learn from our textbooks. May be what they are saying is true but only in the case of a monatomic molecule. If one considers a diatomic molecule there are two atoms that means two spheres and if it is polyatomic there is...

It is the curve or arc of the circle the bob is following.

Hey what' difference between the kind of communication (Radio Waves) we are having now and the one created due to a varying magnetic field?

So, you said that a time-varying magnetic field you get also an induced electric field, if we can transfer data through magnetic flux then we will be able to even charge the phone or a lap that is receiving the signal at a certain frequency simultaneously! Please correct me if I'm wrong and...

I was not saying about storing data but transferring data wirelessly (like wi-fi) but using magnetic flux and not electromagnetic radiations. Magnetic field has no effect on a adult human till 5000<mew>(micro)Teslas[Even after that there is no signs of cancer]. But electromagnetic field can...

There is a difference between a electric and a electromagnetic field right?

Generation time is the time taken for a cell cycle which includes all the phases I had told you before.

The period between two successive cell divisions is called Interphase or the resting phase. This is the time during which the cell decides to either divide or stop dividing (Note: it is in the case of animal cells because plant cells have special cells called the meristematic cells which are...

Magnetic fields are less harmful than electric field and also a lot safer than being exposed to electromagnetic radiation. If data transfer is possible through magnetic flux then cancers and all those kind of diseases can be avoided. So, the question again is can a magnetic flux(movement of...

Thank you.

Hi I am a pre-university student from India. The reason I came into PF was that there is an amateur scientist competition, so wanted to get some ideas for that. What else...I hope my questions get answered and get new ideas.
