  1. Well what I said about the baseball bat and about choking up was a bad example. Ypu wasted your own time.
  2. A video might be better. Here is a video of a man swinging a golf club in slow motion. As you can see the head of the club is moving faster than the handle because it has to cover more distance in the same amount of time.
  3. The tip is covering a greater distance if you're swinging the stick in an arc. Another example is when you swing a golf club, the head of the club is going to be moving faster than the handle because if has to move a greater distance in the same amount of time.
  4. Well swinging a baseball bat is just one example, Im talking about when any kind of stick is swung how the tip of the stick will be moving faster than the base because it has to cover more distance in the same amount of time, I believe that's called angle of transverse and Im just asking if I'm correct in that.
  5. So Im a bit uncertain about what angle of transverse means but I believe its this, lets say you swing a baseball bat, the barrel of the bat, the part of the bat that hits the ball is going to be going faster than the handle of the bat because it has to cover more distance in the same amount of time. Therefore with a longer bat the striking surface is going to be going faster than it will with a stronger bat and therefore it will send the ball further. So when batters choke up on the bat, when they move their hands closer to the barrel of the bat, they might get more control but they're sacrificing speed and power because in doing so you are decreasing the angle of transverse and thus the striking surface will be moving slower, you're using a shorter bat so to speak.
  6. Pop star Katy Perry recently went into space for about ten minutes or so in a Blue Origin space flight. When she got back, she acted just like this guy Howard shown in the clip below.
  7. With airplanes they have to be both light and strong. That being the case, is it possible to make an airplane that's bulletproof? Can they make an airplane that's strong enough that bullets can't penetrate the fuselage?
  8. Yes it is more like a loop but plants don't feed off living things (most plants anyway, there are exceptions such as the Venus Fly Trap.) Plants only feed off sunlight and nutrients from the ground, and are eaten by animals, which then might be eaten by other animals and so forth. Thus all the food in the food chain, or food loop or food web or however you want to look at it, can all be traced back to the plants. It was high school biology. High school is where I took biology, in college I studied psychology and physics.
  9. But the food chain starts with the plants, so that makes the plants the producers. That's what I was taught in biology class, that the producers are at the start of the food chain. If you're not at the start of the food chain you're not a producers, which means all the producers are plants.
  10. Nope animals are just consumers, it's the plants that are the producers.
  11. So from what I know about the eco system is that it's got producers and consumers. The producers are the plants that take in sunlight to undergo photosynthesis and to grow. That provides a food source for consumers, the consumers are the animals that eat the plants and animals that eat other animals. So the food chain starts with plants and then herbivores and then predators and so forth. However, the plants are always the producers and the animals, whether they be herbivores, carnivores, or omnivores, are always the consumers. However, I would think there are some cases in which a life form can be both a producer and a consumer. There are some plants that in addition to using photosynthesis will also feed off of other life forms as predators, perhaps the best known example would be the Venus Fly Trap. In addition to the Venus Fly Trap there are other plants that also eat insects so I would think they would be both producers and consumers, is that correct?
  12. Ants are extremely strong for their size. Apparently ants can lift over 1000 times their body weight. As such, Im wondering how ants would be on planets with really high gravity, much higher gravity on earth. They would probably do just fine I would think.
  13. Yes NASA has set the groundwork for SpaceX and other space companies but the way I see it NASA will be playing less and less of a role in space exploration in the future, even if it doesn't go away completely. For now, but Im talking about in the future.
  14. Yes I have thought about buying SpaceX stock as well as Blue Origin stock. But now we have UPS and FedEx that do much of the deliveries too. I know UPS and FedEx mostly deliver packages as opposed to letters but they are both very reliable companies and. people will often use UPS and FedEx over the postal service if they're mailing packages or anything bigger than a letter, even though the postal service mails such stuff too. Furthermore I don't get why we have to pay to use the postal service (if you're mailing a letter you have to put a stamp on it which costs money) if its government provided because something that's government provided means our taxes pay for it, unless you want to consider buying stamps just another type of tax, much like tollbooths on highways. The big limitation with government organizations such as NASA providing space travel is the limitation on how much money the government decides to spend on NASA, very few of our tax dollars go towards NASA like it or not. This isn't the 60s, the 70s, or even the 80s. We're not in the space race with Russia like we used to be. Not just Challenger but also Columbia, and it's not really NASA I blame but the people NASA hired for upper management. Some of the engineers knew that Challenger would be a disaster beforehand and they tried to warn the higher ups but the higher ups wouldn't listen. With Columbia they could've launched a rescue with Atlantis but they didn't, again I blame the people hired as management. NASA has done much to help us learn about space but much of that was done when we were in the space race, we're past that now. You mentioned Buzz Aldrin, one of the men who walked on the moon. That was back during the space race and since then the government has not funded any program to send anybody else to the moon, not since 1972. Why? The biggest reason is the simplest, the government hasn't seen any reason to send anybody back to the moon. But that's how it happens whenever new places are discovered and space is no exception. Just look at history, back when people first started crossing oceans that involved sailing across the ocean on a big ship that were only available to the really rich and really privileged and to the best of my knowledge such ships were provided by the various governments of the day. When the new lands were discovered (the Americas) more and more people wanted to go and private companies started taking over ocean travel. Today you can cross the oceans by simply getting on an airplane and flying across, an airplane that would belong to a commercial company such as Delta, United Airlines, American Airlines, ect. so traveling around the globe has gone the way of the private sector. Like it or not that's how I see it happening with space travel too in the future. That's how its happened in history. Ocean travel used to be very risky when you had to spend months on a ship and sail across so I doubt there were much in the way of private companies investing in that. Then, as ocean travel became more and more safe, and faster, more private companies got into it. Now it's almost entirely private companies that do it. My point is that the future of space travel is going in the direction of the private sector. Not to bash NASA but that's the way it's going.
  15. Like it or not space exploration is going the way of the private sector. As it's been mentioned in this thread there's companies such as SpaceX and Bellend One and no doubt in the future there will be more private space companies still. That's how its always happened with travel and exploration throughout history, it starts out as something that is government funded and then goes the way of the private sector and more and more people are able to do it.
