  • My 2010 Turkey data

    Updated: 2010-11-27 00:17:59
    This year we cooked a 12.5 lb turkey, again with the goal of achieving the USDA recommended 165F temperature throughout without any of the turkey going considerably above that temperature so as to minimize drying out of the breast meat. This is essentially a problem of optimal temperature control, to achieve it I started the [...]

    Updated: 2010-11-20 17:37:59
    I thought I’d try out the new image capturing functionality in Mathematica 8 on my Linux based laptop with built in webcam but… In[1]:= ImageCapture[] During evaluation of In[1]:= ImageCapture::notsupported: Image acquisition is not supported on Unix. >> Out[1]= ImageCapture[] That makes me a sad panda!

  • How many MATLAB toolboxes make a Mathematica 8?

    Updated: 2010-11-18 00:39:40
    Out of curiosity I wondered how many MATLAB toolboxes I’d need to buy in order to get similar functionality to Mathematica 8.  I’m not claiming that Mathematica has all of the functionality in these toolboxes since it clearly doesn’t.  Additionally, there are many MATLAB toolboxes for which Mathematica has no equivalent at all.  With that [...]

  • The Tippe Top

    Updated: 2010-11-13 13:35:35
    The Tippe Top is a half sphere connected to a cylinder. If you spin it quickly it flips upside down. How can that happen? There’s a lot of complicated physics involved, but the linked article above does a good job of giving you the basic concept. In this case, friction is a necessary component, the [...]

    If you love your code…set it free!  That’s what Will Robertson did when he released the first version of colorbarplot for Mathematica.  I liked what he did but it didn’t do quite enough for my needs so I added some stuff to it and a new version was born.

  • Does force exist? How useful is Calculus?

    Updated: 2010-11-04 03:45:08
    Frank Wilczek has a great article that gives a philosophical account of why F=ma is so successful even though “force” is fairly close to tautologically defined in that equation. The truth is, it’s a bit like a high level language for computer programming, it covers up a lot of details (at the atomic level and [...]
