Primus2112 that's a tasty setup mate, but to be perfectly honest you're not gonna get far in terms of street/park skating on it. Those are great boards but designed for transport rather than tricks.

Not that there's a problem with that at all if it's what you'd like, but if you wanna do flip tricks you'd be much better off with a street board.

Sorry to be a Debbie Downer


I'm not lookin to be Tony hawk or anything, but I'd like to know a few cool, low risk things to do that are reasonably cool looking and sort of impressive to non skating plebs

Primus2112 Ah gotcha

I'm always gonna recommend a street board over a cruiser/longboard/penny, but there's some stuff you could still do on those. Ollies, no-comply tricks, transition skating (half pipes and bowls etc) should be fine. The stuff you wont be able to do is like kickflips and things like that.

Anyway, good luck man!

One of you genius bitches answer me this:

So GR says that a massive object warps the fabric of space-time, such that a dip is created around the mass and the effects of gravity is created when other objects enter into the lip of the dip. This is often shown in layman's term with a heavy ball in the middle of a trampoline like surface. But this demo is very circular and confusing, given that it is relying on gravity itself (the ball wouldn't depress the trampoline surface if it wasn't for gravity).

So a few questions:
1. how is the massive object bending space-time without gravity being an external force?
2. how do orbiting objects keep their momentum at the lip? In the trampoline demo, the orbiting balls would keep funneling downward and eventually collide into the central mass due to gravity and friction.
3. how does this phenomena translate into the effect of gravity here on earth?

...modes and scales are still useless.

other people can probably answer better than i but i'll give it a shot

1. because through general relativity, gravity isn't described as a force. it's a result of uneven distribution of mass, ie empty space being right next to a planet or a star. the imbalance creates the curve of spacetime, which creates the effect of gravity. so it isn't that gravity is causing the curved spacetime, but is rather a result of it

2. really complex/lengthy/annoying maths involving angular velocity/acceleration/momentum. there's a really specific sweet spot in orbiting radii where, once left, the object will either overcome the gravitational pull and leave orbit, or succumb to it and collide with the orbital centre.


basically in angular kinematics and centripetal motion and stuff and whatever, acceleration is always pointed inward, and velocity is always tangent to the path it travels. if you have a sock and put a battery in it and swing it around the acceleration is always pulling the object toward your hand (the centre). but the velocity of the battery (ie the speed and its direction) is always perpendicular to that acceleration. the two 'forces' (velocity isn't a force i just can't think of a better word) have to be in perfect balance, otherwise the path of motion is changed.


3. well through the example of the trampoline the gradient of the distortion (the steepness caused by the heavy ball being pulled down) the strength of gravity is going to be stronger the closer you get to the centre of the ball. on earth, the strength of gravity is stronger the closer you get to the core. so the further you are from the earth's centre (ie your altitude) the weaker gravity will be.
there are other influencers as well but here's a little graphic done by NASA showing the various gravitational deviations on earth:

1) think of gravity as stretches and contractions in the fabric of space time as opposed to a force if it helps. Extreme mass distorts an otherwise “flat” space time fabric so that, for lack of a better explanation, straight lines appear curved and objects travel along them.

2) angular momentum. but basically every orbiting body is degrading in orbit towards massive object that it’s orbiting

3) an orbiting object with sufficient energy will escape orbit and never degrade, or they will eventually enter the atmosphere and break up or be destroyed. If you put a wall around the ball on the mattress and it stopped a marble that wasn’t rolling towards the center, that’s a decent analogy for the earth’s surface stopping you from falling to the center

The best way to wrap your head around orbits is to magine yourself falling off a cliff, but as you fall, the cliff (the spacetime) rotates away from you, pulling you along with it, so you are in a continual state of falling. This repeats in a circle, thus creating an orbit.

I wouldn't say I have an encyclopedic knowledge of anything, but I just pick up shit as I go along. 

Things I know a lot about
- Films
- Videogames (not so much newer stuff, but I'd say games from the 00s are my wheelhouse)
- Music
- Game Of Thrones (just started the books, but seen all of the tv show)
- WWII
- London (although my knowledge deteriorates as you get further from the centre)

Things I'm ok with, but would like to know more about
- Music theory
- Recording techniques and music technology (I took a degree in it, but haven't sat down in a studio in a while)
- Guitar maintenance
- Cooking

Things I would like to know more about
- Amp maintenance
- First aid
- DIY
- Languages (I've tried learning foreign languages several times, but never stuck it out)
- Coding
- Writing lyrics
- Painting

donender, what about Breaking Bad and/or Better Call Saul? 

Oh yeah, I'm pretty clued up on that - it just feels like an age since I've watched either (despite BCS Season 3 airing earlier this year), so i kind of forgot about it. I looked back at one of your earlier posts and I agree on the piano thing. I've had a piano in my house 10 years, and have no excuse for not taking the time to learn it properly, other than the fact that I get impatient if I'm having trouble with something. 

Also, I think my display picture is about 5 years overdue for an update.

I know true knowledge comes from knowing you know nothing.
I also know what I know, and sometimes, I know that I don't know.

I also learned if you kiss and tell online, and your partner(s) find out about it, they don't like that. and also, kissing and telling, people don't want to read that either.
