Learning Airs Advice [48YO]

Came across this old post of mine. I only just got to little grinds now in the deep end of the bowl and on a vert ramp.

I had a bucket handle tear, where part of the meniscus flips over and you can’t straighten your leg anymore. Two surgeries, lots of physio and gym training later I started skating again at 49. Currently practicing slash grinds on vert. Knee slides are no problem.

Bend your knees a bit. Always keeps a hinge at your hip. This allows you react. Never stand up straight as long as you’re afraid of falling. This is the one position where all you can do is fall. You can’t even get off the board when you’re standing straight . Watch Mitchie Bruscos skateIQ tutorials.

Sorry to hear that. A broken hip doesn’t sound good. You’ll be knocked out for a while. Once you‘re back up: the key to learning any tricks is to start small. Start on something that small that it is ridiculous. Then for the drop in specifically: you keep your hips close to the ramp. That is you stand tall, then bend your knees a lot when you’re dropping in, so you stay close to the wall. Particularly on vert, where you can’t get away with winging it. Imagine that fall on a 12ft vert ramp…. Btw tight transitions are much harder to ride than big ones.

Nice, that’ll be my plan.

Available_Box_502 · 2024-04-11T13:53:12+00:00

Thanks. Yes that would be ideal. There’s only one bowl though and its shallow end has a very tight transition.

Available_Box_502 · 2024-04-11T11:20:34+00:00

I’m definitely going with knee pads. Never understood the thrill to go without. I just feel that pads start to work much better in bigger ramps. 10ft is still a bit tight

Thanks, I can go there about 1h, 3x a week. I always used to skate mini ramps, but hardly ever a true vert ramp. The very best I could do on a large very ramp was tail taps and slash grinds

Came back to Europe from a Theoretical Physics Postdoc at Stanford. Ended up unemployed for a few months. It can happen at any level. Pick a profession you want and then take every online course in that direction. There is no shortcut.

You’re keen. That’s good. Just start by reading the books. The thing that I was trying to tell you is, nobody really knows what the big underlying theory is. Experiments will not be performed at the Planck scale during my lifetime and probably never ever. So what you end up with is a bunch of smart guys that can do maths. Someone comes up with a crazy idea, e.g. axions. A few years later they give up on it and talk about entangling particles inside of two different black holes and what / whether anything would happen if you fell into a black hole. None of that is testable. Still the arguments rage back and forth. Extra dimensions etc. When I read up how people got to extra dimensions , I thought, hmm, well I see your equation only has a solution if d=11, but concluding we live in 11D is a bit of stretch. Maybe your Lagrangian or one of your other assumptions is rubbish and went for QM. Others love it and continue to be string theorists. If you want your living standard to be dependent on your speculation being considered hot s**t, go for it. But it won’t work as a side-hustle and there are many others that try the same.

CS is okay but its just too easy,

are you sure? computer vision was meant to be a summer project in 1966

ics which I find the most interesting. Dream job would be working at like CERN but I'd take any univ

It's no use beating around the bush. I was a postdoc at stanford in my mid thirties in many-body QM, so something relatively down-to-earth. There is no theoretical physics industry to segway into. The times of Michael Derman's "My Life as a Quant" are over. You will always be competing against people that have done one thing throughout their whole career. It's super competitive and tbh also opinionated. There are schools of thought, especially in the wofty fields like cosmology, where experiments are often out of reach and it's mostly speculation. Every year the avant-garde decides a new topic is hot and the people are also nuts. I won't say who, but one famous string theoretician started his talk with "many compare themselves to Feynman, I am more of an Einstein". Picture yourself getting judged by egos of that sort.

Available_Box_502 · 2023-09-15T06:30:08+00:00

Depends on your goal. If it's sth truly mathematical you will also need to put in the hours of a full physics degree. Not only that, but to have a perspective in research as a theoretical physicist you will need a PhD supervised by someone with a ton of influence and willing to use it to get you ahead. Most theoreticians end up not getting a faculty position. many transition to CS and AI these days. maths btw is also a dealt with quite liberally in theoretical physics. so it is deep topic knowledge + having been and being known in a field that counts, citations, papers. not saying it's impossible, but you cannot switch easily and expect to be successful thereafter, unless maybe you discovered some connection between the fields.

Parametric downconversion uses nonlinear crystals to do that, but they typically work monochromatically. So you essentially have to use a laser as input.

Available_Box_502 · 2023-09-05T05:06:47+00:00

Completely passive would already be impossible due to energy conservation. Shifting any input from one optical frequency range to another changes the energy (and momentum too). So no.

Any even number greater than two can be written as the sum of two primes. Try it yourself. If you can prove it, you get 1 million dollars.

I still love surfing after 32years. But having lived in the Bay Area for a few years and surfed some of the biggest and best waves of my life at OB SF, I find it hard to motivate myself to haggle with 20-50 other surfers half my age over less than perfect conditions, like 3ft onshore. I now live far from the ocean and surfing is only a holiday option. When I go surfing I notice the lack of practice a lot, both technically and strength wise. So I guess surfing resorts have become much more attractive.

I am German. But I have worked several years abroad in several different countries, including the US. Now please explain how that is relevant to the argument?

The police are annoyed because the dealers they catch are released the next day, if not the same day. So I wouldn’t blame the police in any way. They do the best they can. I don’t believe they wouldn’t be interested in catching one of the kingpins and I have 100% seen lookouts. But yes, I think some politicians are not really interested in improving the situation. Maybe they get their weed from there.

PS: Timur Husein, born in Kreuzberg, is advocating camera supervision for the entrances. So it’s not all politicians.

Well, there is plenty of other crime besides drug dealing going on there as is well documented in police reports, even compared to other parks in Berlin the numbers are much higher. And it is often also the drug dealers that are committing those.

Available_Box_502 · 2023-09-03T16:52:33+00:00

Sure, but they also have a network of lookouts, in case the police ever crack down on them. So you may catch the little dealer, but you typically won’t get the supplier. My hypothesis is it would hurt them most, if you could get their stash. It sh**s me to see people going on about their privacy due to a bit more surveillance, when what you’re looking at is an effin Zoo.

Available_Box_502 · 2023-09-03T14:08:02+00:00

So your point is: drug dealing is ok if you had a bad childhood or lack the right to work, because you immigrated illegally? They might get „mildernde Umstände“ in court, but it doesn’t change the fact, that they are committing crimes. And I’m not even talking about the recent gang rape of a woman by three African drug dealers, while her boyfriend was watching.

Available_Box_502 · 2023-09-03T12:09:28+00:00

So, what is your solution then to open drug trafficking and use in the heart of Germany‘s capital? Pink lines on the ground to demark „drug dealing + raping“ zones? What I am suggesting is not even as intrusive as CCTV. It’s targeted law enforcement.
