Graphic: ketchup bottle problems solved

Ever get frustrated with the leftover ketchup stuck in the bottom of the bottle and try to use a knife to get it out???


Well, look no further for a solution to that problem. Plant researchers, inspired by the near frictionless surface of the Pitcher (type of plant), have found a way to have the ketchup not stick to the bottom of the bottle.

Can you think of any problems this will cause besides the one mentioned in the article?

Physics Jokes Anyone?

Ever wonder if you could tell your friends some funny physics jokes to get them more interested in a topic?

Well, below is a few to make you chuckle. Tell me your favorite one and why it's funny in class for some extra credit.

Gravitation can not be held responsible for people falling in love.

What did the thermometer say to the graduated cylinder? "You may have graduated but I've got many degrees".

Rene Descartes sits down for a meal at a Parisian restaurant. The waiter asks for his order and he orders a hamburger.The waiter asks, "Would you like fries with that?"Descartes says, "I think not," and instantly disappears.

What happens when electrons lose their energy? They get Bohr'ed.

A neutron walks into a bar and orders a beer."How much for the beer?" the neutron asks the bartender."For you?" replies the bartender,"no charge."

Are physicists really crazy?

Can we all agree that most physicists are a little bit crazy?


Well, in Isaac Newton's case, he wiated almost twenty years to publish his results from an experiment where he had formulated and numerically checked the gravitation law. His original conclusion was formulated by 1666, but wasn't published until s1687 in his book Principia for the pure reason that he could not justify his method of numerical calculation in which he considered Earth and the moon as point masses.


So, not only did Newton wait twenty years or so to publish his results, he also invented a type of calculus-based mathematics in order to solve his calculation problem.

Concluding, Newton's Law of Universal Gravitation states that:
Each mass particle attracts every other particle in the universe with a force that varies directly as the product of the two masses and inversly as the square of the distance between them. In equation form this looks like:

F=-G[(mM)/r^2]e_r.


What other equation have you seen that looks similar to this but applies to point charges?

Calculus Anyone?

How do you feel about using a TI-89 calculator?

Are you aware of all of the functions your calculator has?

Well, follow this link below and take a look. The video more describes calculus than the functionality of your calculator, but it is fantastic.

What is one thing that you know about calculus? (Not how you feel about it, but the actual content matter in the course.)

Keys to Success in Phys 100

Ever wonder what it takes, I mean what it truly takes to be a successful student?

Well, we all want to get straight A's and be on the President's List every semester through the easiest route possible.

I find that the best thing that works for me is making a schedule and writing down each task that I need to accomplish accompanied by the due date. Doing this, allows me to do my best to make sure that all of my homework gets done on time.

What is something that will help you to be a successful student?

Is this Real?

As all of you know, YouTube.com can be a very addicting web site, can't it? Have you ever browed the videos of kittens? They are hilarious and guarantee to make your day better.

Below, is the link to a unique video that demonstrates a physics phenomena. I want you to take a look at this video and see if it is real. Can you find any trick photography using the skills you may have learned in film class? Is this really possible?

A few sidenotes:

-There is no sound to the video, so if you can't here anything then it is the correct one.

-The liquid they pour on top is, I believe, liquid nitrogen.

ARCHIMEDES' PRINCIPLE

ARCHIMEDES' PRINCIPLE

Students of physics are frequently told

Of experiments performed by great physicists of old

Like Boyles and Charles -- but greatest of these

Was the Principle discovered by Archimedes.

The Sicilian King, Archimedes was told,

Ordered a crown from a large lump of gold,

And though the weight of the gold was completely correct,

The goldsmith's eye made the King suspect

That he'd made up the weight with some cheaper metal

And stolen some gold, that his debts he might settle.

His problem was then of outstanding immensity

As he had no idea, whatsoever, of density.

Climbing into a bath he received a surprise

When he noticed the water beginning to rise.

He suddenly snapped, and let out a scream,

As he realised, with joy, his long-wished-for dream.

He found the upthrust, produced on a body's base*,

To be equal in weight to the water displaced,

And soon volumes and weights would make it quite plain

What various metals the crown could contain,

And so he could easily show to his Royalty

The absolute proof of the goldsmith's disloyalty.

Leaping out of the bath at remarkable rate,

He made for the palace by doorway and gate --

But the men in the street were completely confounded

To see a naked man shout "Eureka! I've found it!"
