X-ray

X-rays are a type of electromagnetic radiation. Electromagnetic radiation can have many different wavelengths. For a particular range of wavelengths we get visible light, for another range we get ultraviolet, and for yet another we get infrare [...]

Resolution of Lens

It wouldn't directly match a real-world camera... but read on. On most digital cameras, you have orthogonal pixels: they're in the same distribution across the sensor (in fact, a nearly perfect grid), and there's a filter (usually the "Bayer [...]

Computer Science VS statistics

I think that there is a fundamental difference between statistics and much of current computer science type machine learning. In statistics we rely on the evidence and tend to factor out as much bias as possible. In machine learning in the [...]

Scattering Vs Diffraction

In simple words, scattering occurs when light hits a surface and reflects off it ... Therefore scattereing of light makes an object visible to you....On the other hand, diffraction is bending of light around sharp edges or slits. Diffraction i [...]

Computer Program - Work and design

Hi,Computers don't do anything without someone telling them what to do, much like the average teenager. To make the computer do something useful, you must give it instructions in either of the following two ways: Write a program that tells a [...]

Electric motor - Function

First of all, all motors function based on interacting magnetic fields. These fields are created by the supply currents that power electromagnets.Now, we have 2 major types of motors, the DC and the ac induction and ac synchronous motors.I wil [...]

Stars twinkle , planets don't ?

Just to be more clear lets first count the types of objects in the night sky: Stars Planets Artificial satellites Natural satellites (moon) There are other objects like nebule and star clusters etc. but let's for the time being ignore them [...]

Science and Life

As you know friends , I am Chetan . Today I'm going to write about Life, and definitely our life is related with science . Today we can save our time in any work with the help of science . Guys human improve his speed in each improvement . Let's w [...]

Theory of Genetics

I assume that you know basic biology and would like to know about genetics. So we'll begin with cells. Cell is the basic unit of life. That means, a group of proteins, lipids, water molecules, and other compounds which had some affinity on [...]

Nuclear power plant - Function

Fission plants are the current standard and consist of all nuclear plants operating. They work by having a nuclear fuel arranged in rods placed inside a reactor core. Nuclear fission works by hitting a fissionable material such as Uranium 235 w [...]

Wrinkles - Physics of wrinkles

Heat and water cause wrinkles. Heat breaks the bonds holding polymers in place within the fibers of a fabric. When the bonds are broken, the fibers are less rigid with respect to each other, so they can shift into new positions. As the fabric c [...]

Ohm's law

Law states that Voltage and Current are directly proportional, and the proportionality constant is collect R V=R×IV=R×I Voltage is also an archaic word and concept to indicate a potential difference (also referred to as V or ΔV), that is the [...]
