50th Anniversary of Doctor Who: The Physics of the TARDIS

Posted by mattusmaximus on November 23, 2013

In honor of the epic 50th anniversary of Doctor Who, I am going to re-post a recent post I made this past summer: SkepchickCON-CONvergence 2013 Day Two – Physics of the TARDIS…

On my second day at  SkepchickCONCONvergence 2013, I participated in two panels.  The second panel was titled “The Physics of the TARDIS” and since the con had a “British Invasion” theme to it, Doctor Who was a big hit this year.  And that meant that this panel was very well attended, so well attended in fact that it ended up being standing (and sitting) room only!  In this panel we got into all manner of questions regarding the physics, realistic and speculative, regarding time travel, the TARDIS being bigger-on-the-inside, and more.

My co-panelists for this discussion were Steve Manfred, Renate Fiora, and Katherine Krantz.  Check out the audio of the panel below, and enjoy!  🙂

SkepchickCON-CONvergence 2013 Day One – Time Travel in Film

Posted by mattusmaximus on July 14, 2013

Well, I’ve been back from SkepchickCONCONvergence 2013 in Minneapolis, MN for about a week now, and I am finally getting caught up on everything.  As usual, it was an absolute blast, and I recorded all the panels in which I participated.  On the first day I participated in the “Time Travel in Film” panel, wherein we discussed in what movies has time travel been done well? Does bad time travel make it a bad movie? What are our favorite time travel movies?

My co-panelists were Charlie Jane Anders, Courtney Okey-Wernimont, and Sean E. Williams, and I took it upon myself to inject a bit of realism into the discussion, since I’m a physics professor.  However, despite me trying to be a wet blanket, we had a rousing discussion which I hope you will enjoy 🙂

Edmund (Pseudo)Scientific at it Again: This Time They’re Selling an “ESP Lamp”

Posted by mattusmaximus on June 20, 2011

You may recall that I made a blog post in 2009 – titled Edmund (Pseudo)Scientific Sells “Ghost Detectors” & Other Woo – wherein I strongly criticized the science teaching outlet called Edmund Scientific for caving in to the “ghost hunter” fad. They started to sell all manner of goofy things: ghost detectors (which are actually just electromagnetic field meters) and even DVDs on remote viewing. And all of this from a science teaching catalog – you might as well turn to the biology section and see creationist materials for sale!

[**Addendum (6/28/11): to get a good look at why I view such claims about EMF meters “detecting ghosts” so skeptically, take a look at this post – Convergence/Skepchicon Day 2: Ghost Hunting & Evidence Review – which outlines that so-called ghost hunters, when pressed, basically admit they aren’t doing any serious science.  But they want to look like it]

Well, not to be outdone in their tumble down the rabbit hole, Edmund (Pseudo)Scientific now has for sale an “ESP Lamp”.  I kid you not – they claim this thing can actually read your thoughts… as in extra-sensory perception… as in psychic woo-woo… and it only costs about $200!  But don’t take my word for it.  Read their own description of the product:

Edmund (Pseudo)Scientific’s “ESP Lamp and Money Burner” 🙂

Lead your own experiments in the mind’s possible influence on machines, PSI testing, and more with this colorful LED lamp. Four different color LEDs are lighted dependent upon a random number generated from a miniature Geiger counter included on the back. You may even figure out how to use it to tell the future. And, when you need a break from the lab, it makes a very interesting lamp too.

I’ll agree that it makes an interesting lamp, but that’s about the only thing in the description that’s factual.  Everything else is pretty much pseudoscientific gobble-dee-gook because many decades of research has clearly shown that no such phenomenon as ESP exists.  And that part about “telling the future”?  I suggest just saving your money and buying a Magic 8-Ball, because it would cost a LOT less and give you just as accurate results! 😉

But, sadly, that won’t appear to stop Edmund (Pseudo)Scientific from catering to the lowest common denominator in their quest for a quick buck off the gullible.  Unfortunately for them, they don’t seem to have done the math on the other side of things: how do they think science teachers across the country are going to react when they see this sort of garbage for sale in their catalog?  I know that I’ve spoken to a large number of science teachers who are quite upset about this (and justifiably so) and who are boycotting Edmund.  I’m among them, and I encourage all of my skeptical colleagues (especially those teachers among us) to do likewise: until Edmund (Pseudo)Scientific pulls products like this “ESP Lamp” and their “ghost meter” from their shelves – or at least until they advertise them in an honest and scientifically-accurate fashion – we should refuse to give them any business.

Time Traveler Caught on Film? More Like “Whackjob in a Youtube Video”

Posted by mattusmaximus on October 30, 2010

Oh my… some days something crosses my email inbox, and while a part of me says “this is just too silly, let it go” another part of me insists that this is simply something which must be dealt with in the most appropriate manner: by mocking it for the laughing stock that it is 🙂

Case in point: there is a video circulating on the Interwebs of a filmmaker, George Clarke, claiming – seriously, believe it or not – that he’s seen old footage from a 1928 Charlie Chaplin movie which “proves” the existence of a time traveler!  His evidence consists of his claim that he’s seen what appears to him to be a mobile phone in the hands of a woman in the film.  I’m not kidding, you just have to watch this stupidity in order to believe it…

At the 0:40 point in the video, he makes a blatant argument from ignorance: “Nobody can give me an explanation for what you’re about to see.” Using this sloppy reasoning, he goes on to state later in the video that the only possible explanation has to be that she’s a time traveler holding a modern day cellphone (presumably one which has been upgraded by The Doctor 😉 )

I think the best response I’ve seen to this silliness came from a post on the JREF Forum regarding this claim via an appeal to Occam’s Razor. I share that post with you here…

So which is more likely? That someone figured out how to travel back in time and once doing that, figured our how to travel through space roughly 886,973,634,480 miles (based on the Galaxy’s speed of approx 552 Km/s and the travel of 82 years and not counting leap year days or current time vs time that the shot was filmed)? And mind you, that’s not counting in the orbital speed of the Sun in the Galaxy (220 Km/s) over that time.

-or-

That someone of advanced age (and possibly diminished hearing) is wearing and holding onto a hearing assist device of the era?

I know which one I’m putting my money on.

So, because MR. Clarke states that “it’s unexplainable” then he’s going to explain it by appealing to time travel?  Personally, I think that leprechauns are a much more valid explanation, because I simply cannot explain it any other way!  ‘Nuff said.

The Large Hadron Collider – Where Does Science End & Pseudoscience Begin?

Posted by mattusmaximus on October 20, 2009

Where does legitimate science end and questionable pseudoscience begin?  It’s a good question, and one brought up in my mind due to a story about the theory behind the Large Hadron Collider (LHC) which has gotten a lot of attention in recent days.  Two theoretical physicists have come up with a theory by which they propose to explain why the LHC might never detect particles like the Higgs Boson… sabotage from the future.

Yes, you read that right – sabotage from the future. I’ll let the article explain it a bit more…

The Collider, the Particle and a Theory About Fate

Then it will be time to test one of the most bizarre and revolutionary theories in science. I’m not talking about extra dimensions of space-time, dark matter or even black holes that eat the Earth. No, I’m talking about the notion that the troubled collider is being sabotaged by its own future. A pair of otherwise distinguished physicists have suggested that the hypothesized Higgs boson, which physicists hope to produce with the collider, might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather.

Holger Bech Nielsen, of the Niels Bohr Institute in Copenhagen, and Masao Ninomiya of the Yukawa Institute for Theoretical Physics in Kyoto, Japan, put this idea forward in a series of papers with titles like “Test of Effect From Future in Large Hadron Collider: a Proposal” and “Search for Future Influence From LHC,” posted on the physics Web site arXiv.org in the last year and a half.
