Quantum foam is the term used by physicists to describe the violent activity of the quantum world. When you combine all of the characteristics of quantum mechanics such as wave functions, probability, and uncertainty you get a pretty active interaction among the forces and particles. You can also think of it as a quantum soup, happily bubbling away.

Quantum electrodynamics , or QED , is the theory that describes the way electrically charged particles interact with one another and with magnetic fields through the exchange of photons. Also known as relativistic quantum field theory , it's quantum because it includes all of the quantum characteristics like probability and uncertainty; it's a field theory because it includes Maxwell's electromagnetic field equations; and it's relativistic because it incorporates the concepts of space and time from the special theory of relativity.

Quantum physics (AKA quantum theory or quantum mechanics) is a branch of physics providing a description of the behaviour and interaction of matter and energy on the scale of subatomic particles, photons and certain materials at very low temperature. The quantum realm is defined as being where the "action" (or sometimes the angular momentum) of the particle is within a few orders of magnitude of a very tiny physical constant called the Plank constant.

A set of exercises suitable for homework problems is located here: Exercises. The later chapters don''t have as many, but more will be added in the future.

Note 1 : Although my other books deal with physics, there is no physics in this book. It''s just a fun introduction to probability.
Note 2 : Calculus isn''t a prerequisite, although a few of the problems do involve calculus. These are marked clearly.
Note 3 : This book is between two and three times as long as the draft version I''ve had posted on this webpage for many years. So there''s a huge amount of new material.

Whether students need or don’t need homework is a question that has been discussed for years. Both sides of the argument make some valid points, but neither is perfect, so the debates continue.

In order to make your own decision on which the better method of education is, you need to consider every factor. You can start with the arguments that explain why students don’t need homework:

If you do a google search for "quantum mechanics homework", you will get lots of sites that post homework and solutions. This one seems to be quite a reasonable homework #1 for a QM course: http://www-hep.phys.unm.edu/~seidel/VEF/VEF-QM-HW-revised2.pdf

I m struggling with this one myself. Start by treating the orbiting electron like a current. I=q/time, dt=circumference / velocity

USE DIMENSIONAL ANALYSIS! 450mL x (1L / 1000mL) x (795g / 1L) = 358g. 3 sig figs ****** do you understand this? ****** This problem, and all of those conversion problems, are designed to teach you that method and to teach you how to use sig figs. If you learn it, your grade will be better. You will an easier time on exams. You ll spend less time on homework and more time.. texting friends or whatever. This method IS COVERED in every modern chemistry textbook. It s taught by every decent instructor. It s required in university level classes. And most instructors at the college level, even in the UK, Gibbs, dock points for incorrect sig figs. You need to learn it. If you don t understand it, ask questions. I ll check back later ****** My apologies if you re not Norrie, Gibbs. You sound just like him. He was an angry arrogant grumpy 75 year old man from the UK who constantly wrote poor answers here on YA and attacked everyone around him. Just like you do and are. To your questions. First, I m not sure why you re asking questions of me in that particular tone. I ll let you explain. Here are a few answers. (1).. I do answer questions in the CHEMISTRY section here of YA. Almost all of the questions posted here are indeed BASIC as you have pointed out. Do you see any "use pertubation theory to estimate the solution to the schrodinger equaton for lithium?" Oh wait. you re not even 3rd year yet. My apologies for bringing up quantum mechanics. I don t write the questions here on YA do I? I just give the answers. (2).. Do I criticize your answers because you re not using dimensional analysis and not using sig figs? You betcha! There are reasons we teach those topics to students like you. And, if you truly were a top student, you would know what those reasons are and your answers would reflect this. They do not, however! (3).. I have no contacts, friends, mates, acquaintances, followers, students, colleagues, etc that "work with me" here on YA to hunt anyone down. This board is anonymous. I m anonymous. No one here knows me. Sure they read my answers and know OF me, but no one knows who I am. And, unless you re really stupid, you haven t told anyone anything about you either. So again, when you call me a "stalker", which I simply cannot possibly be, what you re really doing is attempting to discredit me. Why is that important to you? More importantly, if your answers are getting thumbs down, it has nothing to do with "stalking" It s simply because people disagree with you OR don t like your tone. (4).. Where I spend my time is my business, not yours. When I have free time, I have no problem helping students. Why is that an issue to you? Students like you, should be grateful, not spiteful. (5).. I manage an R&D group for a US based company. I travel around the world to customers and to our various manufacturing sites regularly. Sometimes I sit in hotel rooms bored to death (or airports) and write answers here instead of reading boring emails. What s it to you? my questions to you. (1).. how arrogant are you? You challenged Pisgahchemist to an "academic" showdown. You stated your grades were more impressive than his? You attacked the fact that he is a US based instructor and claimed "the UK educational system is better"? You even called him an old man. Who do you think you are? (2).. Why are you writing in this tone? You re just a 2nd year chemistry student. Barely just begun your education. You ve taken 1 general chemistry and maybe 1 organic chemistry class and you re challenging people who have the degrees and decades of experience teaching this subject matter to students to showdowns? You ve already lost! (3).. Do you behave this way in class as well? Want a slightly more challenging problem? try this http://answers.yahoo.com/question/index;_ylt=AlLc86zyDzxLutDyUQJtB8rty6IX;_ylv=3?qid=20100224153940AAgxotN and this http://answers.yahoo.com/question/index;_ylt=ApfrW4_uxmTfLkUo.HqgpGXsy6IX;_ylv=3?qid=20110915142059AAF1krX Can you see how I m applying basic dimensional analysis in these "chemistry" related problems? See if you can solve either on your own genius, WITHOUT using DA. When you re finished trying, you owe apologies to me, Pisgahchemist, Soc, and hcbiochem. ******** Meosha. My apologies for the chatter. Ask questions if you don t understand my answer.
