How to reach the UConn math department by car.

## Some mathematics |

## Current courses |

## Summer program courses |

(In the fourth lecture a team of videographers appears a little after the 43:00 mark and then sporadically through the rest of the lecture. They filmed me and the students on behalf of one of the sponsors of the summer school.)

## Some pictures |

- Mesmerized by a magic trick.
- Dogsitting.
- Old factorial notation.
- The garden of constants. (5 seems a bit sleepy.)
- Kazan (2012).
- Myshkin (2012).
- Russian Vending Machines.
- Nizhny Novgorod(2015) .
- Kaliningrad (2017).
- World Cup (2018).
- Dubna and visiting Shafarevich (2018).
- Suzdal (2018).
- Vladimir (2018).
- A car in Connecticut.
- A car near Boston.
- A commuter, not a commutator.
- A street I don't live on in Berlin. And another one in Clemson.
- Numbers I don't use.
- Galois theory is a piece of cake. (I had this made for a student's 21st birthday in my Galois theory class during 2015. Note how nicely the zeta is drawn, frankly better than some students wrote it on the homework.)
- A
Kubota
*L*-series, seen near the UConn math department in 2016. You can find out more about the Kubota Standard*L*-series here. According to this page these*L*-series are compact (who knew?). I think the letter*L*in "*L*-series" stands for loader or landscaper, definitely not Langlands. - An appliction of mathematical logic to street signs. If that Google street view link dies, a screenshot is here (look in the lower right).
- An application of advanced math to cooking. Read the label carefully. (Taken from Crisco olive oil spray.)
- A good example of bad kerning.

## If you are an amateur and think you solved a famous math problem, look here |

- Scott Aaronson
- Sean Carroll
- Henry Cohn
- Greg Kuperberg
- math.stackexchange here and here
- Terry Tao

## Reasons to be Cautious in Mathematics |

- Theorems that turned out to be wrong
- Theorems with wrong or incomplete initial proofs
- Eventual counterexamples
- Sequences that initially agree but eventually don't

## Some links |

- Page about recommendation letters
- My brother's page
- Math contests
- An interesting lesson in negative numbers. (If the link is broken, go here.)
- A great optical illusion. (The figures are not really moving. This is due to Akiyoshi Kitaoka. See here for more information.)
- Another optical illusion. (Partial explanation is here.)
- A database of field extensions.
- Some html commands for special symbols, both (Roman) alphabetical and mathematical. (For a more general site, go here or here.)
- Figure out LaTeX commands for symbols by drawing the symbol here.
