The sea wasp jellyfish has enough venom to kill 60 adults
|
view preview
Chironex fleckeri, commonly known as sea wasp, is a species of deadly venomous box jellyfish found in coastal waters from northern Australia to the Philippines. It has been described as the most lethal jellyfish in the world, with at least 63 known deaths in Australia from 1884 to 1996. Notorious for its sting, C. fleckeri has tentacles up to 3 m (9.8 ft) long covered with millions of cnidocytes which, on contact, release microscopic darts delivering an extremely powerful venom. Being stung commonly results in excruciating pain, and if the sting area is significant, an untreated victim may die in two to five minutes! The amount of venom in one animal is said to be enough to kill 60 adult humans (although most stings are mild). ...

Practice makes perfect

Why practice tests should be the first and last step in the studying process.I'm sure you've all seen the bumper stickers or posters that read, "I'd rather be fishing." If I were to stick one of these on my car I'd supplant fishing with coding. You might choose "singing," "eating" or "grooming my chia pet." Regardless of what activity you'd rather be doing, it's pretty safe to say that activity isn't studying. Whether or not you consciously ask yourself before hitting the books, the paramount question when studying is "How can I maximize the time I spend doing this?" Or, in other words, it's all about efficiency, baby. In my humble opinion it all starts and ends with the practice test. When you sit down to study, you have a good idea of where ...

Can listening to music while studying make you more productive?I think one of the most underappreciated joys of college living is the exposure to your neighbors' music tastes. Never having met the two guys living below you, there's a good chance you could still create a fairly accurate profile of them after listening to their… diverse collection of Skrillex, Ace of Base, Lou Bega, and Lil Wayne. I've lived with people who study to Broadway show tunes, Disney classics and Kelly Clarkson ballads. I'm not kidding. I've also lived with people who study in complete silence with nothing but a dim desk lamp to remind them of civilization. There are myriad studies out there on the benefits of listening to music at different times. It calms nerves. It ...

How to electroshock your mood during boring lectures
|

How to "fight the fade" during terribly boring lectures.One minute your eyes are locked-in on your professor and you are taking notes. The next minute, your hand is slowing as your eyelids are being forced down involuntarily. The next minute, your head is making its way backward, ready to bottom out on the notebook of the kid behind you. Suddenly your slumberous motion startles you awake and you are primed to repeat the process. Easy to describe because we've all done it before… and seen it done by the kid next to us countless times more. So how to avoid this most common of classroom fates?The key is to keep yourself involved somehow in the lecture. Taking notes doesn't qualify because you are simply regurgitating information instead of activ ...

Marathon Problems

You've all experienced the 30-minute test problem. How to tackle it?With all due respect to essay questions, math, science and engineering students can't tip-toe their way around answers. Test questions are most often multiple choice or free response… and don't let the "free" fool you – there is only one correct answer. Besides "That test sucked," the most common complaint I've heard exiting the myriad math-based tests I've taken over the years is, "You know that long problem at the end? I didn't even know where to start. SO unfair." I think what's really unfair is that person's right to use the same language as the rest of us… but I digress. Truth be told, it's safe to say we've all had our trying times with lengthy, intricate word problems w ...

The Cost of Absenteeism
|
view preview
The length that some students go to make up for lost class time is befuddling.It's often said that when creating a business plan, if you understand the people you'll be catering to and are really in tune with their tendencies and preferences, marketing your service or product will be a piece of cake. In my opinion, there's no better example of this than "Review Session Gurus," as I like to call them. There are guys that previously attended my university who make an inordinate amount of money by helping under-prepared college students cram for exams. Their service isn't anything special; in essence, they teach the testable material in a condensed form, provide their own notes and practice test and shoo students out the door to prepare for thei ...

Laptops are increasingly popular in the classroom, but are they best for taking notes? Alright, so here’s a topic that I admittedly don’t have much to contribute to: Is it better to take notes the old fashioned way (in a notebook) or is it better to take notes on an electronic device like a tablet or laptop?For the purposes of the classes I took in my freshman year, a laptop was great. I type four times as fast on a laptop as I can write on paper. Being a freshman I also thought it necessary to take an exorbitant amount of notes to cover my bases. Thus, laptop note taking was the way to go. But, alas, as I returned for my sophomore year, my laptop’s battery life was a whopping 48 minutes. That gets me through half of a class if I’m lucky ...

What are the most poisonous plants?
|
view preview
Plants are essential for any ecosystem, being both a food source and habitat for living things. Although plants are stationary, many are dangerous to touch or eat, making you sick or cause a bad reaction. Some of the most poisonous plants are described below: Abrus Precarious or Rosary Pea (Left) This plant has beans that contain a deadly poison. Ironically, their seeds are often used in jewelry and rosary making, but are not harmful when touched, only if chewed or scratched. The poison is known to stop protein synthesis, leading to organ failure. Ricinus Communis or the Castor Bean (Center) The castor bean plant comes from Africa and its seed is the source of castor oil used all over the world. However, the seeds contain a deadly poison called ...
