I brown bag my lunch everyday & starting this week began cutting my turkey sandwich diagonally instead of horizontally (which I have for years). Something seems different with the sandwich cut diagonally. I can't quite pinpoint it but feel I'm getting less of a sandwich cutting it diagonally. I'm beginning to think the angle in which the knife is inserted to cut the sandwich somehow absorbs or erodes its contents. Has anyone else noticed this? Is there anywhere I can find out if this is a fact?

I mean machines needed for research in scientific fields, do we require complex machines, which a middle class person may not be able to get it easily? For example, if a middle class person may want to conduct research on DNA details, will he be requiring heavy and sophisticated systems to conduct such 'experiments' or whatever? If he would be, will he have easy access to those machines? (Keeping in mind his financial status)?

so: when they move, photons have a small mass m=E/c^2, so undetectable gravity has an effect on them
then if you get together lots of photons, the gravity that acts upon them, can we create a material, like a gas or a liquid or a crystal?

My science teacher gave individual problem statements to each student or group and this was the one I was given. She also gave the class some vocabulary words, and I got "Air Pressure". I believe that you can crush the bottle by sucking the air out with your mouth but my teacher says you can't touch it. My friend told me that maybe you can ignite fire in the bottle to suck the air out but it wouldn't be possible because the bottle can melt if it's plastic. My teacher told me so to. So I'm thinking that there has to be some type of machine, instrument or something that can be put at the mouth of the bottle to suck out the air. Please help? I have no idea.
