Follow That Law!

Justices Back Mayo Clinic Argument on Patents

In his opinion for the court in the case, Mayo Collaborative Services v. Prometheus Laboratories, No. 10-1150, Justice Breyer started with first principles.

“Einstein could not patent his celebrated law that E = mc2[sic]; nor could Newton have patented the law of gravity,” he wrote.

In general, Justice Breyer wrote, an inventor must do more than “recite a law of nature and then add the instruction ‘apply the law.’ ”

“Einstein, we assume, could not have patented his famous law by claiming a process consisting of simply telling linear accelerator operators to refer to the law to determine how much energy an amount of mass has produced (or vice versa),” he wrote.

I wonder if some savvy lawyer would interpret the specific mention of linear accelerators to mean that cyclotrons are to be treated differently…

It Doesn't Take a Physicist to Correct a Physics Mistake

Comparing Temperatures

An article claimed — in its headline — that a ~5ºC (~10ºF) increase in temperature was an increase of 18.7 percent, by calculating using the relative temperature scale. Which is wrong, of course; e.g. 2ºC does not represent twice as much thermal energy as 1ºC. The site has since made a correction.

If you really want to do a percentage based comparison, you need to convert to an absolute temperature scale like Kelvin, which shows you that it’s actually a 1.8 percent increase in temperature (306.75 / 301.45). This is middle school science.

Sadly, I don’t think that this is generally taught in middle school. Or possibly even high school, except to a few students.
