I have seen the movie 'The Secret Law of Attraction'. It seems to remind my of quantum physics a bit. However, I read about the concept behind the creation of the movie and have come across a lot of controversy. Some people are saying the law of attraction usually does not take the function of...

Can anyone please help me with a question re the minimum size square steel pipe needed to bear a load. I loved physics but never took mechanical engineering. I am rigging a winch to one end of a pipe to lift a static load (holding up a gangway temporarily to repair). The gangway weighs around...

Homework Statement A uniform circular cylinder of mass `m' (a yo-yo) has a light inextensible string wrapped around it so that it does not slip. The free end of the string is fastened to a support and the yo-yo moves in a vertical straight line with the straight part of the string also...

These braces were installed on the concrete support pillers at ground level of a very large 6 level mall. Would the engineers comment on the safety of this construction, in particular drilling through the concrete support structure

I have several tested and untested inventions that I would like to get some help developing, and hopefully getting credit for. They are: a working model of a mechanical “antigravity device” That creates 2N of lift, weighing 400 grams, a “green” device that can harvest 300v, 0.970 microamps...

Hi, I want to write some articles in a blog. The blog should be a kind of online diary for my proceedings and cognitions in physics and math. I found a lot of blogs but without a directly latex support :( I know I could work with images, like creating the TeX somewhere else and...

According to HadCRU global temperature warming per decade has been .12C with uncertainty intervals of .13C (since 1995) (using Santer17 formula) which given my thoughts of an upward heating bias due to data handling and urban heat island effect still indicates that since 1995 - there has been no...

I have been a Dell fan for about ten years now, but their technical support never ceases to surprise me. I do buy the premium care package, but considering the heavy use my computers get, often in industrial environments, I come out way ahead. What surprises me is how Dell goes out of its...

While having a discussion with my students this week, a topic came up that I found interesting, and was wondering what other people's views were on it. We were talking about patient compliance with treatment (for diabetes in this case) and the role and availability of support groups. The...

in my readings, spivak or elsewhere, I've come across this several times but i don't have the formal training (maturity) to know how to use it. intuitively: by the atlas maps on the manifold, we can chop up a manifold into patchs. for each patch, by smoothness or something, there is a smooth...

I was reading in a book, says \mu is a measure with compact support K in C, meaning \mu(U)=0 for U\cap K=0.. Is \mu(K) assumed to be finite in this case? It doesn't say in the book, but they make a statement which is true if that's so. Is there usually some assumption about measures being...
