This is Q7 from this month’s Advanced Mentoring, and the most beautiful geometry I’ve ever seen on the AMS. EVERYTHING IS CIRCLES! This means you can use power of a point over, and over, and over…

<i>The altitudes from A, B, C of a non-isosceles, acute-angled triangle meet the opposite sides at D, E, F respectively. The line through D parallel to EF meets CA, AB at Q, R respectively, and EF meets BC at P. Prove that the circumcircle of triangle PQR passes through the midpoint of BC.</i> This is Q7 from this month’s Advanced Mentoring, and the most beautiful geometry I’ve ever seen on the AMS.

31.1.18 This is some physics revision from last Tuesday (23rd) that I have only just finished. It’s a poster on radioactivity, from decay to binding energy. I didn’t understand bonding energy initially as I assumed it was extra energy a nucleus has, but I asked my Physics teacher who corrected me to say that it’s actually an energy deficit. Now decay, fission and fusion make perfect sense!

30.1.18 First post! This morning’s free was spent revising Y12 physics in the ILC. I’m a bit rusty on fluids and fluid flow ¯\_(ツ)_/¯

So yeah, if you’re a like-minded studyblr, hmu!
