• ### How do you integrate this Michaelis Menten equation: -d[S] / dt = {V* [S]} / {K + S}?

This is the Michealis-Menten Equation. Integration of it is useful for when the substrate concentration [S] is directly measurable like by Nuclear Magnetic Resonance, but estimating the rate of substrate consumption introduces some error. -d[S] / dt = {V* [S]} / {K + [S]} [S] = substrate concentration V = maximum velocity K = Michaelis... show more

• ### Is my understanding of volume:volume mixtures correct?

If someone asks me to produce 1000 mL of a 7:9 volume to volume dilution of limonene and water, Is that 7 parts of limonene + 9 parts of water in my volumetric flask = 16 parts in my flask? Therefore the volume of limonene (L) that I should add is (7 / 16) * 1000 mL = 437.5 mL of Limonene The volume of water to add is (9 / 16) * 1000 mL = 562.5... show more

I have been thinking about how I do not talk to my brother much. I do think that he is very cool and if I ever talk about him to others I always speak positively of him. But I do not communicate with him very much because I do not think we have much in common. But I think it must be possible to communicate with people who have different perspectives and experiences in life. He is a businessman and I am a scientist. He is a father and husband and I am lonely. He is like 4 years older than me and we live in different cities. We kind of have different philosophies, but he is actually right and practical about a lot of things. I think I have a pretty good idea of what his life is like. But I do not think that he knows what my life is like and I feel pretty guilty about that. First I did not mention it too much because he is more successful than me and I have been struggling, although things are getting better lately for me. So what should I do?
