They might have shut down, but they still have the cutest name! And they've made some cute inscriptions too, see: HHTT
Birch and Swinnerton-Dyer conjecture in two minutes by Ciro Santilli Updated 2025-03-28 +Created 1970-01-01
Summary:
- overview of the formula of the BSD conjecture
- definition of elliptic curve
- domain of an elliptic curve. Prerequisite: field
- elliptic curve group. Prerequisite: group
- Mordell's theorem lets us define the rank of an elliptic curve over the rational numbers, which is the . Prerequisite: generating set of a group
- reduction of an elliptic curve from to lets us define as the number of elements of the generated finite group
The paper that states the BSD conjecture.

Main implementations: the same as electronic switches: vacuum tubes in the past, and transistors in the second half of the 20th century.
How to make an LM386 audio amplifier circuit by Afrotechmods (2017)
Source. Builds the circuit on a breadboard from minimal components, including one discrete transistor. Then plays music from phone through headset cables into a speaker. There are unlisted articles, also show them or only show them.
