“Dave Barry: A Journey into My Colon and Yours”
You mix two packets of powder together in a one-liter plastic jug, then you fill it with lukewarm water. (For those unfamiliar with the metric system, a liter is about 32 gallons.)
“Dave Barry: A Journey into My Colon – and Yours,” Miami Herald, Feb. 22, 2008
Then you have to drink the whole jug. This takes about an hour, because MoviPrep tastes -- and here I am being kind -- like a mixture of goat spit and urinal cleanser, with just a hint of lemon.

The Next Millennium Bug…
• Y2K problem was 2-digit code for year: 2000 and 1900 indistinguishable.
• Now many systems store dates in a signed 32-bit integer representing the number of seconds that have elapsed since January 1, 1970.
• 1 bit used for the sign.• 231 = 2,147,483,648
Today: 1,415,836,800
The Next Millennium Bug…
• 231 = 2,147,483,648 seconds 68.096 yr
• On January 19, 2038 at precisely 3:13:07 universal time, the clock will reach the largest possible representation of a signed 32-bit integer.
• Upgrade to a 64-bit system and the number of seconds represented will take us to Sunday, December 4, the year 292,277,026,596.

Two cars leave a rest area at the same time and travel north on I-95. One car averages 56 mph and the other averages 64 mph. The faster car reaches the next rest area ½ hr before the other. What is the distance between rest areas?
Seismographs record two types of wave energy (P waves and S waves) that travel through the Earth after an earthquake. Traveling through granite, P waves travel approximately 5 km/sec and S waves travel approximately 3 km/sec. If a geologist working at a seismic station measures a time difference of 40 sec between the arrival of the earthquake’s P waves and S waves, how far from the station is the epicenter?
Traveling through granite, P waves travel approximately 5 km/sec and S waves travel approximately 3 km/sec. If a geologist working at a seismic station measures a time difference of 40 sec between the arrival of the earthquake’s P waves and S waves, how far from the epicenter is the station?
• P waves reach the station 60 sec after the quake.
• S waves reach the station 100 sec after the quake.
• The distance between station and epicenter is 300 km.
(5 km/sec)(60 sec)= 300 km

• Find distance between two
consecutive points (spherical
trigonometry)
• Divide by 6 hr to find
speed of forward progress.
Problem reduces to finding the central angle where the points are not oriented due north-south of each other.

Naïve estimates of the CFR (case fatality rate) derived from the ratio of recorded deaths to recorded cases significantly under-estimate the true CFR since the final clinical outcome of over half of the reported cases is not known.

Basic reproduction number, R0, of an infection is the number of cases that one case generates on average over the course of its infectious period in an otherwise uninfected population.

One simple model suggests that the proportion of the population that needs to be vaccinated to prevent sustained spread of the infection is given by:
