    adding, you add 100 to zero. that's 100 * 1. one instance of 100. zero instances of 100 is none.

    Medical Second degree burn two nights ago (explicit)

    i'm sure enough time has now passed for the process to complete. i had a very bad burn under my foot. when i finally went back to ER they said infection was 2mm from the bone. if it proceeded they would amputate the front of the foot. a bone infection is difficult because since the bone is...

    Math Math Grant Proposal Writing Tips & Ideas

    there are a great many experiments in mathematics that require as much computer as can be obtained. if you want to model the universe you need a second universe of equal mass. approximations will be required by people decended from us 10 billion years from now, it simply must be approximated...

    Undergrad Why the universe is expanding faster and faster

    i refer ether to be an anesthetic and solvent, and aether as a medium for light waves. my preference.

    Where do you go for Science News?

    i have read science news magazine since i was 10. 1970. ok 9. theyve recently undergone a new format, but the content is just great. after reading it for 30 years I've read an encyclopedia britannica they are .ORG! not that other 'c' word... www.sciencenews.org well worth a...

    High School Find the equation in the form of ax+by+cz=d

    i'm at the library, i was just looking at those in my crc standard formulas and tables around page 240-250. its a piece of cake but i can't quote them. someone will show up.

    Undergrad Could the shuttle land with Hubble?

    neat idea increased landing speed. keeps lift up. still nice and easy.

    Graduate How are Supernovae Ia and Dark Energy Related?

    what would be, say, a table of sn1a redshift discrepancies that occur parallel to the dimness? would there be a dimness tabulation with that? or where could i find some? sigh, .. relegated to library computers for a while

    Undergrad Q: Can the vector product be factored out from an integral in electromagnetism?

    that one got away from me. i spent my 30 minutes trying to get it right and the system timed me out on editing my post. i left it without a follow up. integral cross product seems to me to be for example int x * a dt pos * acc, that by the liebnitz rule of distributint pairs such as...

    Undergrad Q: Can the vector product be factored out from an integral in electromagnetism?

    i just now happened to have to integrate a cross product. this particular one is from celestial mechanics. the cross product of the sum of the system's m*v cross a, i had to think a minute. then i remembreed because i was doing some of these. that the derivative of the cross product...

    Graduate Hardness of Neutronium: Estimating Magnitude

    i was looking at some fields, with three quarks in the neutron, that combination of them must be harder than the set for the proton. weak force is so strong. and still half life of a proton 10^33y if that and neutron 15 min or so. they can hold back a near-black hole wow

    Graduate Hardness of Neutronium: Estimating Magnitude

    excellent. i couldn't remember names of other scales. i ran across something in a book review i believe about this kind of thing, saying that neutron stars' exterior is a solid crust, but the interior is more of a dense liquid. so the core wouldn't quite be the place to look. that was...

    Graduate Hardness of Neutronium: Estimating Magnitude

    i wasnt being facetious. similar to the charge mass ratio of the electron, what is the next ratio to this state? how strong is the weak force? gravitationally speaking how much mass does a neutron star have, we can start with the core as a natural environment. what kind of pressure is...
