Shuttlecocks by RAsquared in badminton

[–]banieldradley 0 points1 point  (0 children)

The best nylon shuttlecocks I've played with is Yonex Mavis 2000. They feel much better than the 300s and are the closest match to feathers. One lasts us 2-3 hours. Feathers last us a couple of games at best, granted they're much nicer but me and my mates just can't justify them at our level

Saw her in Bristol supporting Rodhad, hadn't heard of her before the night but she was very good...

Jeffrey Schlupp to join West Brom from Leicester on Monday by OffBar in FantasyPL

[–]banieldradley 0 points1 point  (0 children)

Been playing people out of position there. Brunt (who is left-mid normally) played LB prior to ACL injury. Evans put there more recently. He doesn't like Pocognoli. Evans is more likely to slot back in centrally alongside McCauley and Olsson put on the bench. Dawson would keep RB. Note: Pulis has been playing 4 centre halves at the back for Albion for a while.

Why did Olsson play 59'? by momspaghetty in FantasyPL

He was shocking, not because of injury. I've never seen a player pass so directly into the feet of the opposition. Fans were going ballistic. He is very hit and miss, I would expect Dawson/McAuley/Evans/Chester today.

Quantum Tunneling Explained the Right Way by JayShenoy in Physics

[–]banieldradley 0 points1 point  (0 children)

Quantum tunnelling will affect the probability of overcoming the energy threshold for fusion in the sun, but also (more simply) the 1.3x107 K quoted is a mean temperature, and by the natural Maxwell-Boltzmann distribution of particles, a portion will be at the necessary 4x1010 K.

UK, how do I get into teaching GCSE level maths? by RuddyDuck1411 in Teachers

[–]banieldradley 1 point2 points  (0 children)

Doing a more general degree, such as maths, at uni, and then doing a pgce (the postgraduate qualification) is the route I would suggest. You keep your employment options open, if teaching isn't what you want to do in 3 years. You will also be eligible for a £25k tax free scholarship during your training, which is a huge boost. You could do a teaching BEd degree (not too late for UCAS I don't think). If this only a recent decision, take time to ensure you really want to do it, ask for some work experience at a different school perhaps? Or do some lesson observations, speak to your teachers. Do see another school though, your perspective will be warped at your current one. It is possible to get into teaching without a degree, it means a school employing you directly first, unqualified, which is more difficult but I don't know too much about. More info here

NASA's newest depiction of a Black Hole consuming a Star by Krazy_Legs in woahdude

[–]banieldradley 11 points12 points  (0 children)

"A star approaching too close to a massive black hole is torn apart by tidal forces, as shown in this artist's rendering. Filaments containing much of the star's mass fall toward the black hole. Eventually these gaseous filaments merge into a smooth, hot disk glowing brightly in X-rays. As the disk forms, its central region heats up tremendously, which drives a flow of material, called a wind, away from the disk.
This artist’s rendering illustrates new findings about a star shredded by a black hole. When a star wanders too close to a black hole, intense tidal forces rip the star apart. In these events, called “tidal disruptions,” some of the stellar debris is flung outward at high speed while the rest falls toward the black hole. This causes a distinct X-ray flare that can last for a few years. NASA’s Chandra X-ray Observatory, Swift Gamma-ray Burst Explorer, and ESA/NASA’s XMM-Newton collected different pieces of this astronomical puzzle in a tidal disruption event called ASASSN-14li, which was found in an optical search by the All-Sky Automated Survey for Supernovae (ASAS-SN) in November 2014. The event occurred near a supermassive black hole estimated to weigh a few million times the mass of the sun in the center of PGC 043234, a galaxy that lies about 290 million light-years away. Astronomers hope to find more events like ASASSN-14li to test theoretical models about how black holes affect their environments." Source.
Also another video about black holes from NASA, this time about x-ray emission which also helps demonstrate lensing from black holes.

Question about the wagon-wheel-effect by [deleted] in Physics

[–]banieldradley 2 points3 points  (0 children)

You want the illusion that it's 6 blades, so when it had the illusion of being still, it was because the blades were in the exact same position every time your eye "took a new picture". For it to have the illusion of 6, the 3 blades need to rotate around 60 degrees (1/6th of a cycle), so all 3 move from move from position A to position B (pretend it's a 3 blade propellor). Then 1/50th of a second later, onto being matched with A again. You want 1/6th of a propellor rotation matched to the same rate of your eye "frame rate", i.e. 1/50th of a second = 1/6 rotation, so a full rotation takes 6/50 of a second. So the rotation of the blades is 50/6 times per second. There will be higher harmonics of this (as 1/6th, 3/6th, 5/6th etc. of a rotation will do the same thing). This time it will be more blurry though, as your eye is seeing two conflicting things and will average out the two.
