What is Basics: Definition and 378 Discussions

Hi everyone, I'm new to genetics, but would like to start studying it, what would be a good starting book :confused:

I have never encountered phonon before, so I am going to make a list of statements, and please be generous to point out any mistakes. Thank you. 1. There is no new physics behind the idea of phonons: it is just an alternative way of doing things. 2. When one says that there are, say, 5...

what does it mean with " CpG islets "? does it stand for; G is Guanosine and Cp is Cytosine with a phosphate group ? and islets is a small group? thanks for ideas! :smile:

Hello I just recently finshed physics honors on a high school level, but my class because of bad weather, and a tight schedule was unable to go over anything having to deal with automic physics. Could anybody direct me to understanding fussion, and the theories that have been brought up about...

How many accelerations are there in circular motion ? 1) Angular 2) Centripetal 3) Linear is this right ? and if a particle in accelerated motion always experiences an intertial force, does an inertial force act opposite to linear acceleration ?

What are the basics of building/desgnin a hovercraft?

I'm trying to achieve a complete, precise understanding of the differences between these laws. A precise clarification of the following terms as they relate to each other is needed: true, not true, false, negation.

Dear all, Please help me to solve the following problems about Poisson brackets. Let M be a 2n-manifold and w is a closed non-degenerate di®eren- tial 2-form. (Locally we write w = w_ij dx^i ^ dx^j with [w_ij ] being a non-degenerate anti-symmetric real matrix-valued local function on M)...

Hi, could someone give me an explanation of Fourier Series' please or a link that would give someone who has no idea about them a working grasp of what they are.

I'm having difficulties understanding the concept of power and how you generate it in a circuit. Mainly I'm uncertain about how electrical energy can be used to produce power and what are the conditions for producing it (are resistors required?) Would someone be so kinda as to give me an anaolgy...

Now, this question may be incredibly stupid, but it has been bothering me nonetheless. Say you have a basic circuit loop as shown in the picture. Ohm's law: V = RI Now, according to a textbook I'm reading right now, "By Ohm's law, there is no voltage across an ideal (i.e...

I have two identical clocks. They have batterys carrying exact amounts of energy units. They have identical powerful lasers. They have identical gutters. And a spherical piece of matter. All clocks are measurment tools. The laser shines on the sphere. The sphere moves down the gutter (but...

My textbook says the an object undergoing undamped, under-driven harmonic motion (http://romano.physics.wisc.edu/lab/manual/img279.gif) does NOT have its maxima at the points where the displacement curve makes contact with the exponential envelope curve. How can this be the case?? Doesn't...

Have any of you used Carrara 3D Basics? I'm thinking about getting, it's suppose to be an easy to use, very well priced 3D design software that isn't short on features. That's the description though. I've read one review that was positive, have you used it?

Hi everybody, I'm about to apply for a program in molecular medicine and need to freshen up my Physics for the admissions exams... haven't had any Physics for 2-3 years :rolleyes: so I guess I'd better get busy. Most of the final score is math, chem and biology anyway (which I enjoy), but...

Hi guys just had a question. I know about neutrinos and how they act - their being able to pass through matter leaving it as it was but my question was how are what are the basics of neutrinos are they antimatter particles of some particle? Someone please enlighten me, thanks.

Question #1: Can I speak of an atom decaying because one or more of its particles exceeded "escape velocity" according to statistically observed decay rates and a unit of the particle's former affiliation fell apart post-escape somewhat, and the atom was changed into an isotope or some other...

I need some resource(s)[prefbly E-Books] to learn hardwares. Like Networking, Processor Fuctioning etc ... Thanx for any help!

Has anyone here done or know how? I'm looking for a brief tutorial on how to pick somewhat simple locks.

Iam new to the concept of Grid Networking. Can anybody explain it ? Is there any forum/ site to know more on tht subject ? What kind of softwares should i use ? PLz Help !

What is the BCS theory?

I am a high school student who needs help understanding some aspects of Physics. My main areas of deficiency are: Average Speed while falling for time,t: Vave= (1/2)v , and projectile motion on the moon. (1/2)at I am really struggling to grasp these concepts so...

Does anyone know the basics of the local spin density approximation?

These are the topic areas covered in the notes for this article: The Concept of Energy, Work and Power, Potential Energy, Kinetic Energy, Change in Energy, Conservation of Energy, Elastic Collisions http://physicspost.com/articles.php?articleId=178

Could you please tell me what the inputs and the outputs of a VOLTAGE AMPLIFIER are? Also what do these mean (in a voltage amplifier): - voltage gain - bandwidth - distortion - positive/negative feedback ?

In this thread I am basically going to copy over what I posted in a previous thread which describes what I consider to be the four most elementary molecules in life. Lipids, DNA, RNA and Proteins. It is on these four types of molecules that Life is based, and so are the basis for Molecular...

ok in my freshmen enlgish class (this dose have soemthign to do with nano technology just wait) we have to come up with some topics becuase we are adventually doing persawseve essays/speechs ok so why not do soemtghing that no one in the class has any concept of...nano technolgy now i know the...

Can anyone explain to me the red shift
