Not very exciting, but I was sitting near the banks of a lake near my house, and I saw a stream of bubbles emanating from a particular point for about 30 seconds. After a minute, they started again for another 30 seconds. I dug around for a while trying to figure out what it was. I got to the bottom of the lake, and still these bubbles were coming up out of the ground. Any idea what it was?

We are going to have a home inspection done on our first home and we were thinking of skipping the radon test because the basement is not really livable. At the most we would be using it for storage so we are not planning to spend much time at all down there.

However, we were thinking of putting our cat's litter box in the basement. Then I wondered if radon could affect my cat like it would in humans? I know radon can cause lung cancer and do not wish for that to happen to my cat. Does anyone know if it will affect animals the same as people?

A number of simple chemical substances first came together and formed a protein - which is no more possible than a randomly scattered collection of letters coming together to form a poem. Then, other coincidences led to the emergence of other proteins. These then also combined by chance in an organized manner. Not just proteins, but DNA, RNA, enzymes, hormones and cell organelles, all of which are very complex structures within the cell, coincidentally happened to emerge and come together. As a result of these billions of coincidences, the first cell came into being. The miraculous ability of blind chance did not stop there, as these cells then just happened to begin to multiply. According to the claim in question, another coincidence then organized these cells and produced the first living thing from them.

Let (X, M, u) be a measure space. The definition of the Lebesgue integral over X for a function defined on X and with values in [0, oo] is given in terms of simple functions, that is,
Int f du = supremum {Int phi du | phi is a measurable simple function satisfying 0 <= phi <= f}. Some authors require phi to take on only finite values, but others allow phi to take on oo. It's not hard to show that in both cases the value of Int f du is the same. But if we allow simple functions to take on oo, then the standard proof of the Monotone Convergence Theorem, the one due to H. Levy, is not valid, Because, for c in (0, 1) and phi a measurable simple function such that 0 <= phi <= f, we define X_n = {x in X | f_n(x) >= c phi(x)}, n=1,2 ,3 ...f_n being a monotone increasing sequence of measurable functions on X. If we require phi to have only finite values, then X = Union X_n. But if we allow phi to take on oo, then this is not true. That's the reason for my question.

I am interested in becoming a biologist or naturalist. How can I get started in animal care? It would be useful to have experience working with larger animals before hopefully going to university or college.

Alright, so I understand it is the standard explanation for the wavefunction "collapse". But how is it a product of thermodynamics? And how does it prevent interference between the wavefunction and the environment? Please explain!
