Oh noes! I forgot to hang the awesome picture of Frankie in his white tux on prom night!

The bedroom looks like your typical undead sleeping pad. With pictures hanging of friends and family, some undead deer skull, a rickety unfurnished bed, and an empty wardrobe, it's ideal for the everyday vampire who's trying to get away from all the stresses of life. The writing desk at the top of the stairs is in a nice corner by the window(s) so the maximum amount of moonlight is available when writing to those creepy, alive relatives of yours. I also like that there's a railing at the top of the stairs, but no railing following them down to the first floor. Clearly safety is of no concern during the transition between stories.

Go read it. Be enthralled. Clean up your drool on the way out.

(12:43 p.m. EDT) So, Sandy is currently doing his/her (its?) stuff outside my apartment. LOTS O' RAIN!

No snow or high force winds yet, though. I think that stuff is being saved for later.

In other GOOD NEWS, EVERYONE, I'm technically still alive.

UPDATE 2 (3:40 p.m. EDT): Winds have been picking up, rain is unrelenting, and my apartment is cold. This calls for hoodie & blanket times! 8D

Wow, it's really raging out there...

UPDATE 3 (10/30/2012 at 2:29 p.m.): Things have calmed down. This morning whilst being sleepily half-awake I heard cleanup trucks outside. At least two trees are down that I can see from my apartment windows. Fun stuff.

Also, the power went off a couple times last night and this morning, but it's currently on (hence my ability to type this ).

So, school for me has been cancelled Monday and Tuesday due to some sort of sandy storm that is also full of winds and snow (and may or may not be caused by Spongebob's rodent friend). The details aren't really clear. So, after removing things from my porch and storing lots of water in my fridge (at least five gallons worth, maybe more), I feel I'm ready to bunker up and watch it from the comfort of my living room.

My roommate is thinking of going into school to do research. I am not terribly keen on the idea. So, Pokémon it is. 8D

Also, that awkward moment when you're about ready to check out Christmas presents for siblings on Bricklink and a scheduled downtime occurs. :\

Just so everyone knows, I obtained the awesome LEGO Haunted House over Fall Break and have pictures that will work wonderfully in a review. You can probably expect that next week at some point (I hope). For now, let's go over another fun physics equation! This one is probably very familiar to you, though you may not have any idea what it means. I give you mass-energy equivalence:

Where E is energy, m is mass, and c is the speed of light. It's a very simple-looking equation with only three parameters, but what does it mean? Well, it means that anything with mass – you, your cat, your house, the Earth – has latent energy stored in it, and the amount of mass determines that latent energy. For an object at rest, this correlates to the rest mass of the object. If an object is moving really fast (near the speed of light) its kinetic energy causes it to actually get heavier, since the object can never actually reach the speed of light (only objects with no rest mass move at the speed of light).

So, if we have an object sitting and doing nothing, and it suddenly glows for a split second, then stops, where did the light come from? Well, light has energy, as we know, so we could calculate the energy of the light that escapes our object. If the light emanates in all directions, then the net kinetic energy of the object is unchanged. But conservation of energy says that energy can neither be created nor destroyed! Have we violated the laws of physics with our weird glowing object? Well, no, because if you were somehow able to weigh the object pre- and post-glow, you would find that the mass of this object is actually slightly less after the light is given off.

But wait! Doesn't conservation of mass say that matter can neither be created nor destroyed? Well, yes, it does say that. So the only way for this to make sense is if the mass is converted into the energy that was emitted. We know that energy can be converted into different forms (electric, mechanical, thermal, etc.), so this must mean that mass is another form of energy that can be converted to and from! Pretty neat, huh?

Minutephysics has a cool video on this with a bit more technicality and pretty pictures of radioactive cats, but this is my text-based explanation simplified.

Another thing that may cross your mind is that this looks very similar to Newton's second law:

So, does Newton's second law equate force with acceleration? Well, no, because in the mass-energy equation, the constant of proportionality, c^{2}, is a universal constant; it is the same for any and all objects in the universe. The mass of an object, however, varies from object to object, and is thus not a fundamental, universal constant, so while these equations are similar and relate two seemingly different entities, they do not conceptually perform the same task.

So, this past week was my Fall Break, which allowed me to enjoy the comforts of home and gave me the opportunity to say hello to people who are still at my undergrad.

I also received and played intensely Pokémon White 2, hence my lack of blog posts. I just beat the 8th Gym today (Marlon is weird...) and now have to prepare lecture for Wednesday. :\

I had a wonderful time today; I got to see old friends from my undergrad today and went exploring a corn maze; it was a lot of fun.

Also, equation of the day: Newton's Second Law

where F is the net force, a is acceleration, and m is the mass of the object in question. It's such a simple-looking equation, but it contains so much physics. Want to know the path of a free-falling object subject only to the force of gravity? You use this equation. Want to know the attractive force and classical orbit of planets/atoms? You use this equation. Want to know the physics of a car skidding on pavement? You get the idea.

This equation is a staple of physics and is used extensively in intro and classical physics. Newton, you clever devil, you.

So, I've decided to do one of those daily-like blog entries, though I can't guarantee that I'll be able to do this every day (being a busy grad student and all). I figured that, being a physics grad student, math might be one of my stronger suits (next to reviewing LEGO sets), so I'm going to try and share an equation with you and see if I can explain it well enough for people to understand. 8D

Tonight's equation: The wave equation.

This says that the sum of the change in the change in the function, ψ, with respect to the coordinates used to represent it is equal to the inverse square of the speed of the wave,c, modeled by ψ times the change in the change of ψ with respect to time.

This equation is the governing equation for all wave phenomena in our world. Sound waves, light waves, water waves, earthquakes, etc. are governed by this mathematical equation. In one dimension, the wave equation simplifies to

which has the lovely solutions

where A and B are determined by appropriate boundary conditions, and ω/k = c. This equation governs things like vibrations of a string, sound made by an air column in a pipe (like that of an organ, trumpet, or didgeridoo), or even waves created by playing with a slinky. It also governs the resonances of certain optical cavities, such as a laser or Fabry-Perot cavity.

Since waves are one of my favorite physical phenomena, I find it very appropriate to start with this one.
