Revision as of 14:54, 18 March 2024
- March 18: Nathaniel Johnston posts a YouTube video about the discovery of the true period-15 glider gun and period-16 glider gun, and the history leading up to those discoveries.
- March 17: James Pascua discovers the first period-16 90-degree independent reflector based on a suggestion by Matthias Merzenich, using the period-16 glider gun to hassle a honey farm predecessor and produce a banana spark. 90-degree reflectors are known for all periods except 14, 17, and 19 with periods 15, 23, and 26 having only dependent reflectors.
- March 16-17: Keith Amling completes a new c/4 diagonal unstable puffer engine (only the third known puffer engine at this speed) based on a partial result by Matthias Merzenich. Caleb R. Hilton uses sparkers to stabilise the unstable engine into explicit puffers. David Bell uses this engine to construct the first p52 c/4 diagonal rake, and "b3s23love" and Merzenich use it to substantially reduce the size of the p108 c/4 diagonal rake.
- March 12: 400spartans discovers a population-236 solution to the unique father problem with a self-forcing patch containing 389 set (both on and off) cells and fitting in a 22 × 20 bounding box, each of these statistics being the smallest known.
- March 12: David Bell completes the first c/4 diagonal backward-to-sideways glider reflector using reactions by Keith Amling and Matthias Merzenich. Using one of Bell's glider-releasing reactions and a beehive-to-ship converter by Amling, Merzenich constructs the first c/4 diagonal p28 rake and demonstrates the existence of rakes at periods 32, 36, and 40.
- March 1: Period1GliderGun discovers the first true period-15 glider gun using a B-heptomino hassler by Carson Cheng hours after finding the first p16 gun. Period-15 is now the smallest period for which a true-period gun is known.
