About science..
Politics in science is terrible. In business, politics = fighting for money and power. In science, politics = fighting for funding, which you need to keep yourself working, power, and prove that I am smarter than you.
Had sth else to say, but can't remember..

Cool things i saw during fermentation at NUS lab last week..
Liquid nitrogen.. We asked the guy to refill our liquid N2 tank, so he drove this van of liquid N2 here, and while the tank was filling up, the pipe was smoking cos the N2 was so cold. When we poured some N2 into the sink, the water in the sink froze, imagine what will happen if you dunk ur hand in, your fingers will drop off or sth.
Frozen

Pink solution. There's this pink foamy solution that's used to kill bacteria. When we poured it into the media containing bacteria, the orange media turned yellow and things started coagulating inside. Then when more media is added, the yellow thing turned brown. eew. Sick

Bottle caps. Bottles of all sizes have the same size bottle caps.

Cuvettes and Eppendorf tubes. It's really difficult to spill liquid from them, especially cuvettes, cos the meniscus of water and cohesion, adhesion prevents the liquid from dropping out. So must turn the entire thing 180 degrees upside down to pour out the liquid.

Bioreactor. The tiny 2l bioreactor that we used looked exactly like the one in Soper, or Mr Chan's lecture notes, except that all the probes go in from the top. In the real world, not like in Physics design questions, you can't just poke a hole in the middle of nowhere and stick a probe in..
