  • It is known yeah. Another user commented it. If you take a wing and put it in a wind tunnel you can put sensors in its wake to measure the pressure. By manipulating the fluid flow you can change the pressure. So low pressure on top and high pressure on bottom. Multiply that by the surface area and you get a force. Smaller force on top of the wing, lower force on the bottom of the wing. So the wing goes up. Of course theres some physics going on in the fluid that explains the change in pressure, but this is just a quick and simply-put explanation because I took a fat amount of zquil and am tired.

    Edit: I had to do this in a wind tunnel during one of my undergrad courses. It was fun playing with the wind tunnels, would recommend


  • I got a perma ban from reddit. Ive said this in other comments but I’ll add it here: A mod locked a post I was looking at and said something about how the post wasn’t good (I can’t remember exactly what the mod said). I responded by telling to the mod “get lost”. I got perma banned from that subreddit. Then like 5 months later I smoked some weed and, for whatever reason, felt the need to message the mod and say “spank spank spank. Thats the sound I make as I spank you. Yes yes yes. Thats the sound you make as I spank you”. Thats when I got a phat perma ban from the admins. I made another reddit account on a vpn. All seemed well until I launched reddit with the vpn off by accident. My new account was banned shortly after this. Either way, after the first ban I was looking at alternatives. I found the lemmsters. I still have the reddit app with my perma banned account. I can browse reddit all I want but I don’t use it for anything other than porn or when I google something and a reddit link pops up where my question is being answered. There are things I miss about reddit. Primarily I miss the large chess community there. It is far more developed than the chess community on lemmy. I wish I could get the chess community going here. I don’t really miss reddit for anything else. This is evident by the fact that I could’ve been on reddit right now, but instead I prefer to browse lemmy. I really like the fediverse idea. It interests me greatly and I hope to see it grow! One thing that is exciting that I missed out on with reddit is being there from the beginning. I know lemmy/fediverse is newer so I am happy to join during the more early stages and see how the fediverse as a whole grows.







  • That depends on exactly what you are looking for and what level of play you are at. A general source that I do like for these sorts of topics is Chess-Networks series “Beginner to Chess Master”. I think its well put together and easy to understand/digest for beginners. Its free (youtube) which is also nice. Of course you can find many more like these on youtube. I just like Chess-Network for this type of series a lot.


  • Hobby: Chess

    Tips: Ill state a few mistakes here that I see beginners do a lot (mistakes that I also made as a beginner and had to learn to not do and why not to do them).

    1. Don’t give check just because you can give check. Beginners love to just check you with zero follow up. Its like it creates a sense of purpose for their moves but without a proper follow up it is a waste of a move.

    2. Consider the fact that I can make moves and formulate my own plans. Half the game is what you play and the other half is what your opponent plays. If you only consider your moves/plans, I, and any chess player beyond a beginner, will easily beat you.

    3. Every move has a purpose. If you make a move and I ask you why you made that move and you cannot provide a reasonable reason, then you either wasted a move or got lucky and just happened to guess a good move.

    4. Dont try to learn opening theory as a beginner. You should learn the three main opening principiles (develop you pieces, get your king to safety, and control the center of the board) and some very common lines to play but after that you should move on to the middle game and end game. Revisit opening theory once you understand the game at a deeper level. It will make it easier for you.

    5. You paid money and spent time travelling to tournament. You have over an hour on the clock and you oppenent just made a move. Stop and think for a moment. Dont rush your moves and try to play instantly all the time. You waste time, money, and the day since you played like shit (whats the point?).

    6. (Last) Do NOT have an ego or underestimate your opponent. Especially of they are a little kid. There are two types of kid chess players: the ones who learned how to play 5 minutes ago and the ones that humble you. Very little in between there. There are two types of (non-kid) chess players: those who think a 10yr old kid by default sucks at chess, and those who have played enough kids to realize what the fuck is up. It is funny to watch the former turn into the ladder. Those kids at tournaments are such wild cards
