This article describes seven ways to ruin your professional reputation. While this seems to only apply to people with career-type jobs, it is actually very applicable to your academic reputation in the classroom. You can think of your teacher as your boss, your classroom as your workplace, and your coworkers as your fellow students.
Here are the 7 ways:
- Make Excuses
- Miss Deadlines
- Don’t Prepare for Meetings (or Don’t Prepare for Class)
- Be Too Tit-For-Tat (or Expecting Special Treatment)
- Be Unresponsive
- Make Self-Deprecating Jokes (or Have No Self-Confidence)
- Underestimate the Details
Ever wonder why your fingers get “pruney” after being wet for a long time? Scientists now have an answer to the pressing question of why hands and feet get wrinkled after too much time in the bath: Pruniness may have evolved to make it easier to handle wet objects.

A German company has test fired a 50kW laser. It was able to cut through a 15mm thick steel girder from 1km away. Then, as if that wasn’t enough, it shot down some drones from 2km away!
It went undetected for five years on Wikipedia, but now a seemingly meticulous entry about a 17th century conflict between colonial Portugal and India’s Maratha empire has been outed as a hoax.
Here’s a list of other Wikipedia hoaxes. Think before using Wikipedia as a source!
In November, there was a total solar eclipse visible from Australia. A solar eclipse happens when the moon passes between the earth and the sun blocking the sun’s light from a small part of the earth for a short period of time. This video is a time-lapse video of the eclipse. You are watching the shadow of the moon pass over the landscape.
Phil Plait, aka the Bad Astronomer, is very good at debunking bad astronomy. His first book, which is quite good, is titled “Bad Astronomy.” (seeing a theme here?) In this post on his blog, he explains why the world isn’t going to end on December 21st. An excerpt:
Here’s the deal: According to the doomsday prophecy, the ancient Maya predicted the end of the world would occur on Dec. 21, 2012. We know this because that’s the date their calendar ends. While they weren’t specific about how Armageddon was to come about, there are a host of astronomical events that can and/or will occur that can reduce the Earth to a burned-out cinder.
Except not so much. Not a single thing I wrote in that previous paragraph basks in the warm glow of reality, despite being repeated ad nauseum by doomsday promulgators. It’s all nonsense, garbage, taurine feces, flim flam, and pifflery.
How so? Well, it just so happens I know a bit about this, and will happily (though grumpily) be your tour guide through this latest in a long (and, ironically, unending) series of dead-wrong end-of-the-world claims.
Welcome to the Maya Notpocalypse™.
What would happen if you rode an elevator through the center of the earth and came out the other side? This article has a good explanation of the physics involved. (This is similar to an AP Physics problem that was asked one year.)
