SAT scores, obviously

Identify Exceptional Talent Nationwide. S&T workforce programs should
identify and support all talented Americans across geographies, incomes, and demographics. Exceptional talent is defined by demonstrated technical ability, not background or identity. Agencies should therefore anchor selection processes in criteria predictive of STEM success, such as reasoning assessments, domain competitions, engineering portfolios, and technical work, rather than relying on self-selection, essays, institutional referrals, or polish and credentials. Agencies should leverage merit-based identification mechanisms that cover as many people as possible (e.g., SAT scores or
other standardized quantitative assessments) to find overlooked talent.

Could you imagine if the AAS publicly posted frank summaries of the strengths and weaknesses of everyone on the job market? (cf. www.nfl.com/draft/tracke...)

PLAYER ANALYSIS

Allar looks the part with prototypical size and an effortless arm that can make any NFL throw. However, inconsistent touch and ball placement are a major hindrance. In big moments and big games, he hasn’t proven he can rise to the occasion or sustain efficiency. The stats looked good in a conservative offense as a sophomore, but his play became more erratic once the playbook was opened up and more responsibility was put on his plate. He can be slow to process and get to his best option. He also struggles to adjust his pre-snap plan to fit the coverage. It’s worth noting Allar’s receivers struggled to win man-coverage matchups for him. Against zone, he makes anticipatory throws and beats coverage at an adequate clip. Mechanical fixes are possible, but confidence, poise and recognition must be the foundation of any rebound. Allar projects as an average backup with high-end traits.

PLAYER ANALYSIS

Pavia is a short, tough, productive quarterback who plays bigger than his measurables. He elevates those around him and was the main character in Vanderbilt’s shift from doormat to winning program. He’s improvisational, creating explosives that aren’t on the call sheet without playing reckless hero ball. He scans through progressions, throwing with intermediate accuracy, but impatience versus zone can lead to costly mistakes. He can stand and deliver or escape and win with his arm or legs when pressured. However, he lacks ideal mechanics and needs altered launch points for cleaner sight lines and release points. His deep ball is below average. He isn’t explosive or fast, but he’s a force multiplier for the run game, especially near the goal line. Efficiency and success rates check out across most situational filters, but he requires a more tailored scheme. Quarterbacks his size rarely make NFL rosters, but his competitiveness should be a plus as long as he’s willing to accept a role as a backup.

Poking around Google Maps near Hormuz, I learned about Nahwa: a UAE territory inside a part of Oman called Madha which is itself entirely inside the UAE. en.wikipedia.org/wiki/Nahwa

With your advanced degree you have the opportunity to train the AI in your specialized skills. Astronomy 🔭 may be economically worthless but xAI wants you to train it anyway: www.remotech.ai/jobs/space-s...

Getting rich isn't necessary: given academic salaries, the excess provided by median private sector wages would be enough to employ one (or more) postdocs... www.aip.org/statistics/s...

Instrument building is a long journey (I started on ZTF in 2011!), so it's nice to take some time to celebrate.
