  2. In the last decade, the uprise of mobile devices with touchscreens has been prominent, and there are 2 main types of touchscreens. The first, and cheaper style, is known as resistive, which uses 2 separated films that when come in contact they allow current to flow. This is what is used to determine the location of the touch, as wherever the current is flowing is where the user is currently touching. The issue with this system is that it requires physical movement of the plates, meaning it can be triggered by anything pushing it together, also if it's layers are no longer even they can touch i
  3. Conventional light bulbs use a filament, something to run current through that will heat up and produce light. These are very inefficient however, as more energy is put towards producing heat than light. This is why the idea for CFL light bulbs came about, which use a current running through gas to produce it's light. This method is more efficient, but still isn't perfect. This is where LED's come in, as they are small, very efficient, and require little power to produce a good amount of light. The reason why all lights haven't been replaced with LED lights is because of their cost, which whil
  4. Duct tape is famous for it's ability to hold things together, as it's adhesive is incredibly powerful. Duct tape is made with a woven fabric to make up the tape, which could be made of nylon or polyester. This is then coated with a layer of thin polyethylene, which makes up the tensile strength of the tape. This can hold upwards of 65 pounds before snapping, despite how thin the tape is. This makes up partially for duct tape's strength, but where it really shines is the adhesive. This adhesive is made up of rubber compounds, aimed at longer lasting bonding with the material. Normal tape uses p
  5. The point of a tank's armor is to protect the crew inside from bullets, shells, and anything that may be potentially dangerous. The first tanks used metal plates that weren't too thick to protect from bullets, as that was all that was necessary. As the technology advanced, more armor was being put on tanks, so bigger guns were being used to break through this armor. This raised the issue of weight, as you can't just continue to add armor to a tank to make it safe, because the weight would make the tank immobile. The solution, then, had to be far more complicated to allow the tanks to maintain
  6. Everyone knows what Godzilla is, and the creature's exploits in destroying cities, but not many question the possibility of such a creature's existence. Godzilla is 355 ft. tall, and weighs 90,000 Tons, meaning that he is massive in both size and mass. This is equivalent to the size and weight of a cruise ship, but it's capable of walking around. With all this weight to tote around, is it even possible that Godzilla would be able to walk around, let alone simply stand? Well, seeing as his weight is equivalent to $3 trillion in gold, it would take a lot of effort to move him around. He would ne
  7. Altimeters are used by many people in a variety of different situations, such as skydiving, flying, and even hiking. The purpose of an altimeter is to give the user a readout of their current altitude. This can be achieved in many different ways, but the most obvious method is to measure the air pressure. By taking into account the current temperature, one can calculate their current altitude. In early aircraft, this was done with analogue meters, rather than digital calculations. They weren't the most accurate, but still worked very well considering what they were being used for. Now, there a
  8. Ever since the earliest days of the car, suspension systems have been in use to keep the ride comfortable. Seeing as how commonplace it is for cars to have good suspension nowadays, we often take for granted just what these systems do to make our daily that much more comfortable. There are many different kinds of suspension, almost every kind involves a sort of spring. The earliest system to be used in cars was a simple spring on the frame connecting to steering frame, allowing for some amount of movement inside the car. Another type of suspension was the "leaf spring" suspension, which consis
  9. The culture based around the idea of parkour is a sport entirely based around momentum. The idea is to be able to control your movements to be able to maintain your momentum while running around. Normally parkour involves a lot of vertical movement, as well as large horizontal movements. The difficulty comes from having the strength to pull yourself up and over obstacles, or if you're good enough being able to stay at speed and direct your momentum to allow for fluid movements in all directions. Classic examples of this are wallrunning to cross a gap, or using a corner to jump to a higher heig
  10. Space travel has used many unique forms of propulsion, such as solid fuel rockets, liquid fuel rockets, ionic thrusters, etc. The newest type is still debated as to whether or not it is even possible. The EMDrive seems to break the laws of physics, as it outputs more energy than it takes in. The inventor sent a prototype to NASA to be tested to confirm his claims, and their tests confirmed it. This whole concept has yet to be accepted, as it is such an outlandish thing, but it is currently being put through peer review. The implications of such a technology would make it incredibly easy for sp
  11. I found this software a while ago called "Space Engine", which can only really be described as a universe exploring tool. It's just a simple thing that allows you to fly around in space, starting from Earth. You control the speed you go at, and I feel this is the only thing to ever really give me a feel for the perspective on how large the universe really is. At first impressions I thought everything I saw was based on reality, but I found out that by default anything outside of what we have observed is procedurally generated, meaning that it is made up randomly by software and clever programm
  12. The kid's movie UP, while serving it's purpose as a kid's movie, isn't exactly known for being accurate in the physics department. In the movie, an entire house is lifted up by nothing more than balloons. This iconic scene is pretty, but is it probable? Discovery channel's Mythbusters decided to test it harnessing a small girl into a ton of balloons, and seeing how many it would take to lift her. They estimated about 2000 fully inflated helium balloons would be enough to lift the young girl, but with a sandbag dummy they found they would need upwards of 3500 balloons. After tying up all 3500 b
  13. Almost every device we use has a thermometer in it, even if we don't know it. They are used to determine whether or not different electronics have overheated, or if they are too cold. They work on a different principle than a typical mercury thermometer, using a resistor that is affected more by temperature than a normal resistor. The changes in resistivity are used to judge the temperature, which can be measured very accurately depending on the quality of the resistor, and the supporting electronics. Not only is this useful for preventing damage to electronics because of high temperatures, bu
  14. A lot of people have used the Kinect for Xbox, and at the time of it's release in 2010 it was a new take on motion control technology. It allowed for control without a controller, by using 3 seperate cameras, 1 of which is a color camera, the other 2 are infared. They are seperated a small amount, just like our eyes to allow for the cameras to get a 3d model of what is in front of it, matched with the color camera to get an idea of the position of the person in front if the camera. This, along with the decent refresh rate of the cameras, makes it possible for the player to use their body to co
  15. I recently watched the movie "Passengers", and I noticed that on multiple occasions what happened was actually accurate. A lot of other sci-fi movies have huge innacuracies that detract from the overall movie, but Passengers showed one really good example of this, which is a large spoiler, so fair warning to anyone who wants to see it. Jim, the main character, is blown out into space with a makeshift shield he had made. When he was thrown out of the ship, his tether broke and he was heading straight toward the thruster on the ship which would have burned him alive. His reaction was to throw th
  16. It's the exact same thing, which is why a lot of watches have a light button that is a temporary backlight
  17. I was first discovered to be colorblind in kindergarten, when the teacher had us coloring, and I grabbed the wrong crayon multiple times. Many people don't fully understand what colorblindness is, how it affects someone, and what causes it. My type of colorblindness is known as "Protanopia". That means I struggle to identify differences between red and green, blue and purple, and sometimes light greens with yellow. Whenever someone finds out I'm colorblind, the question they usually ask is "What colors can't you see?". This isn't how being colorblind is, it doesn't make all color disappear, an
  18. We use microphones all over the place, and most people have one or more on them at any point in time. Most work on a fairly simple concept, using 2 plates. One of them is much thinner than the other, and acts as the diaphragm, the part that moves as a result of sound. The other one is thicker, and works to make the 2 plates into a capacitor. The sound waves change the distance between the two plates slightly, and therefore changes the capacitance of the system. These changes in capacitance are measured and turned into sound via speakers. Speakers work on a principal that is similar but opposit
  19. Each pixel has 3 color filters in front of the backlight, electricity applied to the liquid determines it's opacity, and therefore how much of light goes through the color filter. Essentially, the liquid crystal can be controlled as to how much light is let through, and the 3 different color filters allow the pixel to assume a large array of different colors. Calculators use LCD displays, but without a backlight or any color filters, and only have 2 states for the crystal, fully opaque or fully transparent.
  20. A new type of software development that is being used to create realistic looking water without having large processing times is based off of approximating almost everything. The basic principal is to use a bunch of small spheres, and calculate how they would react in whatever situation, say water pouring out of a pipe. This would look like a large amount of balls rolling out of a pipe, but the real magic happens in the approximations that are used. The software uses how the balls move to judge how the water would move, and make it look like water by making the balls invisible, and adding wate
  21. We spend many hours every day looking at some sort of display, whether it be attached to a computer, phone, TV, or maybe even a car. These displays work on a relatively simple concept of using liquid crystals that change the color of the light that is provided by the backlight, which is usually white. This tech has replaced the old CRT (cathode ray tube) technology that shot electrons at a screen over and over scanning across to form the image. The next innovation in display tech is hopefully something like what Iron Man has in his suit, a type of transparent display. The current tech used wou
  22. A "Clean Room" is what it sounds like, a room which is very clean. There are varying types of them, from the variety used to make watches to those used to produce satellites. The general idea is to prevent contamination of the air, which is typically dust. In order to enter a clean room, one typically has to wear a full body suit that is meant to contain everything within the suit, so no dust enters the room. No makeup is allowed inside, as those types of particles easily come off and float around in the air. The systems that filter what little dust gets into the air are full room air circulat
  23. Every computer has millions, if not billions, of transistors in it. These transistors have one use, to control the flow of electricity. They act as a switch, but without any physical moving parts. Their size is incredible, since they work to allow electricity through on the atomic level, rather than a larger scale. The physical makeup of a transistor allows it to prevent the flow of electricity in one state, but when a small positive voltage is applied to the side, it allows the electricity to flow freely through it. Because of how small we are capable of making these transistors, we are begin
  24. The first microchips didn't need any kind of cooling, they were cooled by just the air around it. Now, they produce enough heat that it needs to be transferred away in order for the chip to function properly. The solution was to create a heatsink, an array of spread out metal fins in contact with the chip to transfer the heat. Over the years, these have increased in efficiency and size. The heat is spread out to the fins using copper pipes, and then fans push air over the fins to move the air away. Current pc hardware is so heat efficient that with certain parts, the fans can stay off and can
  25. I spent a lot of time as a kid on a trampoline, and now knowing the full mechanics behind it is really interesting. Good post!
