| Description: |
Good Math, Bad Math is a blog which exists for two reasons:
For me to ramble about the beauty of mathematics, and try to share my enthusiasm for the subject.
To track down the bozos who use bad math to lie, distort reality, and in general support bad arguments; demonstrate their errors and their dishonesty; and generally mock them.
The blog will also intermittently include me rambling about other obsessions: programming, music, and whatever else interests me.
The beautiful "Good Math/Bad Math" banner was designed by Josh Gemmell. |

A Special Midweek Recipe: Ad-Libbed Cranberry Chutney
It's not saturday, but I've got a recipe that I needed to
write down before I forget it, so you're getting an extra bonus.
I usually make a simple cranberry relish for thanksgiving. But
it needs to be made a couple of days in advance. This year, I completely
forgot about the cranberries until this morning. So I figured I needed to
do something else. A good chutney sounded nice. I went hunting online,
but couldn't find anything that sounded good, so I went ahead and ad-libbed.
And the results were amazing - this is definitely the new cranberry tradition
in the Chu-Carroll household. Sweet, tart, and spicy - it's a perfect
compliment for the turkey.
Creating User-Defined Types in Haskell
(This is an edited repost of one of the posts from the earlier
version of my Haskell tutorial.)
(This file is a literate haskell script. If you save it
as a file whose name ends in ".lhs", it's actually loadable and
runnable in GHCI or Hugs.)
Like any other modern programming language, Haskell has excellent support
for building user-defined data types. In fact, even though Haskell is very
much not object-oriented, most Haskell programs end up being centered
around the design and implementation of data structures, using constructions
called classes and instances.
In this post, we're going t
The Balance of Screening Tests
As you've no doubt heard by now, there's been a new recommendation issues
which proposes changing the breast-cancer screening protocol for women under
50, by eliminating mammograms for women who don't have significant risk
factos. While Orac has done a terrific job of covering this here and
here, I wanted to throw
in a couple of notes and a personal perspective. Read the rest of this post... |
Shameful Innumeracy in the New York Times
I've been writing this blog for a long time - nearly four years. You'd think that
after all of the bad math I've written about, I must have reached the point where
I wouldn't be surprised at the sheer innumeracy of most people - even most supposedly
educated people. But alas for me, I'm a hopeless idealist. I just never quite
manage to absorb how clueless the average person is.
Today in the New York Times, there's an editorial which talks about
the difficulties faced by the children of immigrants. In the course of
their argument, they describe what they claim is the difference between
th
Types in Haskell: Types are Propositions, Programs are Proofs
(This is a revised repost of an earlier part of my Haskell tutorial.)
Haskell is a strongly typed language. In fact, the type system in Haskell
is both stricter and more expressive than any type system I've seen for any
non-functional language. The moment we get beyond writing trivial
integer-based functions, the type system inevitably becomes visible, so we
need to take the time now to talk about it a little bit, in order to
understand how it works. Read the rest of this post... |
