Can we talk about Hannibal’s educational background for a minute?

Okay, you guys know the scene at Will’s house in Digestivo where Hannibal’s doing what looks like some heavy-duty physics before he asks Will about teacups and time and the rules of disorder? Well, this bullshit right here is quantum field theory. In my understanding (imparted to me by my college bestie, @riteofswing, thanks dear), QFT is a subject theoretical physics graduate students can study after a grad-level course in quantum mechanics. I suppose it’s possible for an ambitious undergraduate to pick it up after a rigorous course in QM, and Hannibal is nothing if not ambitious. You know in college he was that obnoxious guy studying super-hard subjects “in his free time”.

So did he study physics formally? Or does he just have a good math background and he’s assuming he can maybe get something out of this? It’s not out of the question for a doctor to have studied physics, my undergrad department liked to remind us that physics students are among the highest scorers on the MCAT… (Did he go to med school in the U.S. or Europe? Do we know?)

Headcanons? Extraneous knowledge that could rule out possibilities? Is Hanni just full of bullshit? Am I ruining this by trying to analyze it?

I kind of want Hannibal to have studied physics as an undergraduate, that would make my lil heart happy, but I want to hear what other people think!

Ask Ethan: Why is there a limit to what physics can predict?

“Why are there these units (Planck units) which you can’t further divide?”

There are fundamental limits to the Universe, in the sense that there are scales where our laws of physics break down. You can’t break matter or energy up into infinitely small pieces, and the same goes – we think – for space and time. But is that necessarily all true, and is that what the Planck scale means? Not quite. Rather, these are scales at which our laws of physics stop giving reliable predictions, as we make these mass, energy, length and time scales out of three constants fundamental to our physical theories: the gravitational constant, the speed of light and Planck’s constant. They do have strong physical implications, but they don’t necessarily mean these scales can’t be divisible further. After all, every particle in existence has a mass far below the Planck mass!

What are the limits to the Universe, and how are they related to Planck units? Find out on this week’s Ask Ethan!

Im going to see the latest Makoto Shinkai film Your Name (Kimi no Na wa) at the QFT cinema in Belfast tomorrow and I’m very excited to see if the film lives up to the MASSIVE success and box office records its been making even to the point its making Spirited Away look over its shoulder a little! 

Directed by Makoto Shinkai who is already pretty famous for directing other great anime films like 5 Centimeters Per Second, Children Who Chase Lost Voices and The Garden of Words. heres just some of the success the film has had so far:
- Grossed ¥23 billion (~US$190 million) in the Japanese box office to date
- Is the second largest gross for a domestic film in Japan (behind Spirited away)
- is the first anime not directed by Hayao Miyazaki to earn more than $100 at the Japanese box office
- Topped the box office in Japan for a record-breaking 12 non-consecutive weekends
- Held the number-one position for nine consecutive weekends before being knocked off the top spot only to return to the top for a further three weeks 
- In China, it became the highest-grossing Japanese film in the world’s second largest movie market and grossed US$81.3 million…

Ok il stop with the boring stats now lol but as you can tell I’m looking forward to seeing it for myself, I know its not going to be Spirited Away amazing or anything as friends who have seen it say its nothing special but hey I’m confident il really enjoy it :D and i don’t think my reaction will be as bad as Hayao Miyazaki who respectfully responded with silence when asked his thoughts on the film heh heh heh! I’m guessing it must have been tough for him to even remain silent on the subject :P

Feel free to let me know what any of you who have seen it think?

I don’t know who to attribute this to. I heard it in a career talk at work.

“Your thoughts become your words. Your words become your actions. Your actions become your habits. Your habits become your character.”

It’s surprisingly compelling if you take it seriously. I bludgeon myself with this virtue pep talk to make myself take the stairs instead of the elevator in the morning. That’s my character: taking the stairs. Surely the stars tremble in their orbits.

Putting all these sketches in one post for easier viewing. This is my Buckyyyyy! Book… and over time I hope to get it filled up with glorious Bucky sketches - WW2 Bucky, Winter Soldier, BuckyCap, BuckyNat, Stucky, all the Bucky variations :) It’s quite small, only 5.5″ wide x 8.5″ high so it’s nice and handy to tote around to cons.

Science: Where Finding Nothing Is The Biggest Victory Of All

“There are lots of stories out there about how physics is broken, and how we need a massive new breakthrough or a paradigm shift to keep the enterprise of new discoveries going. What nonsense! The truth is that the laws of physics we have in place are the most successful sets of laws we’ve ever come up with. They’ve been tested more robustly than any other set of laws ever, and they’ve passed every single one.”

Over the past month, four big experiments looking for new physics have announced their latest results, and all four have come up empty. At the LHC, ATLAS and CMS failed to confirm the existence of a new particle, leaving us with only the Standard Model. At LUX, the most sensitive dark matter search failed to detect anything new. At IceCube, evidence for a sterile neutrino evaporated. And at CERN’s MoEDAL experiment, magnetic monopoles failed to show up. This might seem like a defeat for physicists, but it’s anything but! The Standard Model and General Relativity emerged victorious again, making them the most successful physical theories of all time, having passed test after test robustly and rigorously. There are still mysteries out there waiting to be uncovered, but we’re going to have to dig a lot deeper if we want to do it.

Find out how far we’ve come, and why each new null result is a victory for exactly where we are today!

Hi, my physics teacher has set my class a report on quantum theory, the history, and the contributors. But my google searches are only bringing up quantum mechanics & string theory, or gossip magazines. Do you know any reliable sources, or have any opinions yourself??? Sorry to bother you.

I think what’s confusing you here is the terminology - quantum theory is a broad term used to refer to the study of the very, very small, encompassing ideas like how energy is quantised (packaged into little parcels), the uncertainty principle, and wave-particle duality.

I usually think of quantum theory as interchangeable with the terms quantum physics and quantum mechanics. Other similar-sounding terms such as quantum field theory are usually developments of quantum mechanics. QFT aims to apply QM to subatomic particles, and thus explain each of the fundamental forces (e.g., quantum electrodynamics explains how light and matter interact). 

The history of quantum mechanics, quantum field theory, etc, all bleed into each other so I think you’re pretty safe to start off searching the history of quantum mechanics (a timeline would help!) and trying to fit the pieces together. It’d also be helpful to look up the main players: Dirac, Born, Pauli, Heisenberg, Fermi, de Broglie, Schrödinger, Bethe (who gave a fairly iconic talk at Shelter Island in the late 40s) and Feynman. 

Good luck!
