The physics of Santa Claus

Ho ho homogeneous second order differential equation to all!
My thoughts last night were on the big red one himself. Think of all of those billions of people he has to give presents to, all the cookies and sherry he gets through in an evening... Lets have a look at some numbers here folks.
If he flew over every house, of which there are at least 1,000,000,000 (That's a billion), and there is a distance of about 30 metres between each house (on average) that means he travels a distance of 30,000,000,000m in the evening (the same distance light travels in about 100 seconds).
As he visits all of the time zones, he has 24 hours to complete his route. The speed of the sleigh can be derived from this information: 1250000km/s (Ignoring relativistic effects, which we shouldn't as this speed is 0.417c. Hey, It's Christmas).
This speed is hard to obtain in Earth's Atmosphere. However, as Santa can make any present, and I asked for a super-powerful magnet for Christmas and did not get one, it is safe to say he stole it and his sleigh is powered by magnets.
As for the vast quantity of food and drink, He is clearly American enough to eat all of the cookies, and Yorkshire enough to hold his tipple (no, I am NOT Santa).

Here's a holiday problem you can solve yourselves! The first answer submitted by a reader (authors not included) will win a box of Leibniz Biscuits! more chocolate than a biscuit!

Solve the differential equation:
dy =  (2y)                   (the denominator is 2 squared add 4!!!)
dx     (x^2)

Here's a cracker style joke for you all to share!Why did the chicken cross the Möbius strip?
To get to the same side!

Now, I bid thee Happy Holidays. Fare thee well,

The twins paradox

Due to a lack of things to post, please enjoy a short explanation of the twins paradox in special relativity.

If you understood that, congratulations! If you enjoyed it, brilliant! Next up will probably be an explanation of the Monty hall problem drawn on a coach journey! Isn't this all very exciting? Yes!

And now the dreaded joke - How many physicists does it take to screw in a lightbulb?

Two - one to hold it in place and the other to turn the universe.

Congratulations to Dr. Martin Smalley!!!

You voted Smalley your favourite lecturer so far!
As previously promised, I gave him a cookie (I also gave cookies to all the lecturers I could find as they are such brave people taking on 1^st year physics students)

As pointed out, my last blog post had many grammatical errors, so I’m editing this one in Microsoft word, like a boss

It has since been found that Bowser always uses windows applications to write his blog posts.

Microsoft: Be what’s on the next level.

Now I’m done trying to sap endorsement money from Microsoft [ahem] Let me tell you something about Smalley, the god among people.

Those who turn up to lectures will know that he teaches mathematics with skill and precision, except from those times he makes the odd mistake [He is only a DEMI-god after all]. He is a lovely gentleman; he shared a bottle of sherry out with our maths practical on Friday! (Sorry M5, we polished off the bottle...) Legends say he can solve a second order differential equation in 5 seconds flat. Without a calculator.
I will miss him when mathematics 1 lectures finish. I might opt to do magnetic in the 3^rd year just to witness his charm with numbers. And MAGNETS! He knows how they work, which is talent at it’s finest.
Furthermore, he is the relentless leader of the galactic empire of Physics.

Darth Smallidus shows no mercy at careless students.

That is all for this time children. The soup today was quark, fresh from the neutron star.

Cursed Lab reports! Here are some references for those who take this .doc seriously. A note to that person, find a new hobby.

Also, my thanks to whoever it was who named Smalley as Darth Smallidus in that post on the 1st Year Physics facebook page.
Goodnight everybody! Hope you all get home safetly.

Greetings Earthlings!

We come in peace!

Hello all of you glorious people first witnessing this blog!
This blog is dedicated to all of the best moments of studying Physics at York University
Along with plenty of physics banter provided by the respective authors!

Artists Rendition using Microsoft Paint.

In other news, please vote in our current poll, located to your right! It's seriously important, certainly more important than your lab report/weekly problems/essays/octopush tournament.... The winning lecture will be featured in an blog post, and we will reward him/her/it with cookies!!!!


Now I leave you with a Joke! (Please don't hurt me)
Two hydrogen atoms are standing at a level crossing about to cross a busy road.
One of the hydrogens stops the other and exclaims "I've lost my electron!"
The other inquires "Are you sure?"
"Yes, I'm completely positive!!!!!"

Disclaimer: No hydrogen atoms were ionised in the making of this joke.
Once you collect yourself from the hysterics that put you into, I bid you a good evening

'Twas a quarter past one, and throughout the theatre

Not a creature was stirring, not by a metre

For Greenall had entered, and begun to talk

On rotational dynamics, specifically on Torque

With his mighty words he captured the brains

Of students naive, though they were his to train

Entranced they sat, drinking in words

Storing them dumbly, not even disturbed

At the midway point he began to decline

But he saved himself swiftly, by providing in time

Newton's second law for rotating bodies

Providing many with sad new hobbies

Inertia, angular acceleration so cool

Just shooting some B-ball outside of the school

when a couple of guys, they were up to no good

Started making trouble in my neighbourhood

I got in one little fight and my mum got scared,

And said "You're moving with your auntie and uncle in Bel Air"

I whistled for a cab, and when it came near

The licence plate said "Fresh" and there were dice in the mirror

If anything I would've said that this cab was rare

But I thought 'Nah, forget it, yo home to Bel Air!'

I pulled up to a house about 7 or 8

and I yelled to the cabbie "Yo home, smell ya later!"

Looked at my kingdom, I was finally there

To sit on my throne as the prince of Bel Air.

My face after he revealed the F=MA equation for rotating bodies

Congratulations Pascal!

Here we have a simple closeup of the mighty astroduck's legs (sorry about space being grey, the flash on the telescope doesn't work very well). You might notice the legs are white - this is simply to ensure the fuel passing through them stays at its lowest possible temperature.

The tiny blob on the left foot is Pascal with his enormous hat, congratulations on being our first voter!

And finally, let us end with this:

A student recognises Einstein on a train and asks "Excuse me, professor, but does New York stop at this Train?"

So you've all heard of Henrys per metre, but just what exactly is a Henry?

Well, in the wonderful world of physics, the Henry (symbol H) is the SI unit for Inductance, which is a property of an electrical circuit measuring the induced voltage compared to the rate of change of the current in the circuit. The unit is named after Joseph Henry (1797-1878), an American scientist who discovered electromagnetic induction independently of and at about the same time as Michael Faraday (1791-1867). Below is the definition of a Henry, where,

H = Henry m = Metre

kg = Kilogram Wb = Weber

A = Ampere s = Second

Ω = Ohm J = Joule

V = Voltage C = Coulomb

So there you go kiddo's, till next time, Macracon out.

The magnetic permeability of free space is given by:

The Units, of course, being Henrys per metre.

Macracon and I first came across this in the e/m labscript. e/m is a pain in the backside to say the least.
Cursed particle physicsts! (that means you The Other One!)

First!
