Cryptography - Nothing up my sleeve number.

From what I have read and this briefly, the numbers chosen to make up the hashes and the ciphers are because they "appear" to be random and have a low entropy (thanks wikipedia).

Are there any implementations of Sobol sequences to generate these numbers?

Hi, I am currently seeking a degree in Biomedical Sciences. I was thinking of adding a Statistics minor. Do you think this would help me find employment in the areas of biostatistics or bioinformatics? I realize that most "biostatisticians" have masters or doctoral degrees, but I was wondering if a Biomed bachelors degree with a statistics minor would make me a better candidate for careers in this field. Thanks!

I wish to secure a canoe (18Kg) to the garage ceiling using metal hooks that screw into the wood joists that hold up the floor above.

I intend to use 2 hooks with a screw thread of 8mm diameter, 30mm length.

Does anyone know the breaking strain of a hook like this if screwed into a sound wooden beam? (I assume the weak point is the join, not the metal of the hook)

Suppose that experience has shown that only one-third of all patients having a particular disease will recover if given the standard treatment. A new drug is to be tested on a group of 12 volunteers. It is believed that the new drug will increase the individual recovery rate to one-half. If health regulations require that at least 7 of the 12 patients should recover before the new drug can be licensed, what is the probability the new drug will be discredited even with the expected increase in recovery rate?

How long would it take for the mist from an aerosol spray-paint can to ignite from an open flame, assuming: 1) the room that the can and flame are in is 10'W x 10'L x 8'H and is sealed 2) the spray can's valve is open, and there is an endless supply of material (not just 12 oz) 3) the spray can is up against one wall spraying towards the middle of the room where the flame is 4) it's 70F and 50%RH.
