Students on the 2026 California High School Summer Program

 

Thursday morning on the California High School Summer Program began as usual, with some attending the 7:15 a.m. Mass in Our Lady of the Most Holy Trinity Chapel, while others paid a visit to St. Patrick’s Coffee Shop for some last-minute prop-prep:

Then it was on to the morning’s class — and more Euclid!

Today students wrestled with three of Euclid’s geometrical propositions: They constructed a line perpendicular to a given line in Book I, , then proved that a line standing straight upon another forms angles is equal to two right angles in . Finally, they demonstrated the equality of vertical angles in .

With all these newfound convictions as their foundation, students next inquired whether, with the knowledge from the first 15 propositions, one could form a square that is truly known to be a square. Can they now construct a figure that certainly has four equal sides and angles? They contemplated, giving suggestions and testing different proofs until class concluded.  

Many then attended the midday Mass, featuring a special treat: a student choir, directed by prefect Anna Santine (’22)! The choir, though newly constituted and with only one practice, sounded amazing, filling the Chapel with sacred music.

After lunch in St. Joseph Commons, students headed to their second and final class of the day, where they sought to delve into the first 11 chapters of Genesis. They considered the days of Creation, wondering at the concept of time: a reality in the beginning, or a metaphor for order, or perhaps even something else? Next, they marveled at the Fall and the promises made by God, contemplating how these are fulfilled. Through their discussions, the sections came to new convictions about the Old Testament, seeing it in a new and different light. 

Like last night, a full range of activities are planned once again for this evening — including Theology on Tap and a volleyball tournament — so check the SummerBlog tomorrow morning for a recap!
