Google's cute doodle for the Leap Day (29th February) 2024.

WHAT IS A LEAP DAY/YEAR?🤔🧐
Common/Calendar Year (y)=365 solar days 🗓
Solar/Tropical/Astronomical Year (Y)=365.2425 solar days🌏🌞
Y-y=0.2425; 4*(Y-y)=0.97=1-0.03 (+1 if divisible by 4)
100*(Y-y)=24.25=(25-1)+0.25 (again -1 if divisible by 100)
400*(Y-y)=97=4*(25-1)+1 (again +1 if divisible by 400)

That is to say,
Using logical and modulo operators, the year n is said to be a leap year if and only if:
(n mod 4=0)∧((n mod 100≠0)∨(n mod 400=0)).

In other words, a year is a leap year if it is evenly divisibly 4, except for years that are evenly divisible by 100 but not evenly divisible by 400.

For example, 2024 and 2028 are leap years; 2100 and 2200 are not, but 2400 and 2800 are.

This is our clever method to ensure that our calendar stays aligned with our seasons or Earth's orbit over time. If nothing were done about this discrepancy, our calendar would slowly drift out of sync with the Earth's orbit and seasons. After 100 years, we would be off by about 25 days! So, to fix this, we add an extra day, February 29, to the calendar every four years, with the exception that a year evenly divisible by 100 is not a leap year unless it is also evenly divisible by 400 (as shown in the calculations).

Thinking about how, with all the talk of meddling in the #2020 #president #election, nobody has really talked about the massive #polling #discrepancies in #Florida. I think we were all distracted by #Trump's temper tantrum, but if you go look, #Biden had a several point lead in all polling data, then the actual #vote count leaned over 7 points #Republican from the national average, a historically massive deviation in a state known for fraudulent #elections...

Coincidence, or #DeSantis?

#RicochetMedia has spoken to over half a dozen current and former OMG employees for this story (who have requested anonymity for fear of retaliation), a spokesperson for the newly formed employee union and Mohamed himself. We’ve listened to a leaked audio recording of a Dec. 5 all-hands meeting and confronted #Overstory management about a surprising number of #discrepancies in their public statements.

Making it groove! Entrainment, participation and discrepancy in the'conversation'of a jazz trio

Focusing on a live performance by a jazz trio, this case study examines the wordless dialogical 'groove' between musicians. Building on ethnomusicological theories of interaction in conjunction with the notion of entrainment, the study makes use of in-depth temporal analysis of musical interaction alongside the reported phenomenal experiences of the participating musicians.
This approach provides an intriguing triangulation between subjective experience and 'hard' temporal data and thus moves to a consideration of musical meaning away from the formal properties of a work and towards the dynamic interactions of the players. While the study of pragmatics has undoubtedly been important in the refinement of scholarly research into music performance, this article suggests that a turn to 'groove' may be of use in broadening our conceptions of linguistic interchange.
