HOW TO FLY

“The knack of flying is learning how to throw yourself at the ground and miss” With these words, Douglas Adams helpfully explained concept of flying in his Hitchhiker’s Guide to the Galaxy. But the ground is really big, and, as the Tick so sagely noted, “Gravity is a harsh mistress.” So herein contained is my handy-dandy explanation of how you can impress your friends and family by throwing yourself at the ground and missing: Step one, throw yourself at the ground. Luckily, this is really easy thanks to gravity, which will pull you down to the ground at an acceleration…

A CHEMISTRY STUDENT’S INNER VOICE GUIDE TO ACID/BASE TITRATION

A. INTRODUCTION .: This experiment consists of two parts. The first is designed so that you may screw up and not face any further consequences. The second requires your utmost diligence, as the products from this experiment will serve as the basis of every other experiment for the rest of the semester. .: In the first part, you will use a primary standard solution of potassium hydrogen phthalate (pronounced ‘phth-al-ate’) to standardize a roughly 0.1 molar solution of sodium hydroxide. This is perhaps the easiest exercise performed in any laboratory on campus, and your soul will be crushed as you…

THE BIOTECH GAME OF LIFE

– FROM THE ARCHIVES – In “The Biotech Game of Life,” which is similar to the Game of Life, each player is a scientist attempting to successfully bring his or her biotechnology product to the market. During the game, players will face many obstacles before obtaining a successful product and the first one to accomplish this wins. Below are the instructions, which provides more details on the game, and links to the game board and play money (pdf files). Note, that like the real thing, it is quite challenging to finish the game. – – – Gameboard (312K) $10,000 bills…

D.I.Y. P.C.R. NOTES, APPENDUM, SHOOTING THE BREEZE – WHATEVER

(This post will be updated from time to time, as improvements arise with regards to the MAKE magazine thermal cycler project. For more info, go here) – – – Date: August 25th We repeated the experiment with the 2C adjustment, but obtained similarily non-optimal data as before. This led to recalibrating of our temperture sensor at 0C and monitoring to see if the temperture cycles waiver at the latter cycles (i.e after the first 10 cycles), which was not the case. At that point, we decided to calibrate our temperature sensor in real time with the eppendorf cycler to see…

DNA RESTRICTION DIGEST AND GEL ELECTROPHORESIS: A VIRTUAL LAB

– Click here to launch virtual lab – (Screenshot #1) This is the virtual version of the UBC Advanced Molecular Biology Laboratory’s experimental kit #2 (see Restriction Digest of Lambda DNA and Gel Electrophoresis for details) which features a common and important molecular technique used in laboratories to analyze DNA. This molecular technique can be used to isolate a gene of interest and to identify DNA sequences that are different. This molecular technique is particularly useful in forensics where it is used to analyze DNA from crime scenes! In this virtual experiment, analysis is performed on lambda DNA and will…

TERRY SPEAKERS: THE SUMMARIES

This year’s Terry speaker series was great, and now the SCQ is pleased to announce that summaries are available for all three (as well as the audio of the entire speech). Follow the links, and seriously people – be inspired. Summaries by Peter Ottis from News 101, CITR 101.9FM – – – “The End of Education” by Dr. David Orr (January 13th, 2006) LINK TO SPEECH | SUMMARY Dr. David W. Orr is Professor and Chair of Environmental Studies at Oberlin College. He is best known for his recent work in ecological design including his efforts to build a $7.2…

BREAKFAST OF CHAMPIONS DOES REPLICATION

To begin with, we’ll start with a chicken scratch drawing of a DNA molecule, which you know is double stranded. My poor pathetic attempt at illustration is therefore going to look like this: You also know that each strand of DNA is composed of building blocks called nucleotides, and that these nucleotides are always interacting in a complementary manner. For example, A’s are always with T’s, C’s are always with G’s, Beavis is always with Butthead, etc etc etc. Let’s draw them in like so: What you haven’t been told at this point is that chemically speaking, the two strands…
