​​How Does a Tennis Ball Launcher Machine Work? The majority of tennis ball launcher machines on the market operate using counter-rotating wheels. When the machine is turned on an electric fan draws in outside air which is then pushed into the canister. To protect the fan motor from debris the air passes through a slab of foam as well as a screen barrier. An electric motor powered hopper is used to channel balls into the landing area. During this process the wheels squeeze the balls and put them under intense pressure, thus forcing them into a circular tube which leads to a small opening. This soft, rubbery circular area is called a detent. When the ball is lodged in the detent it creates an airtight seal at the end of the tube. Simultaneously, a plastic flap falls over the entrance which causes pressure to mount. Under pressure method, Eventually air pressure pushing on the ball overpowers resistance from the detent. This causes the ball to shoot down the barrel and onto the court. When the pressure has been released the entrance flap is released and another ball is able to enter the tube. The process is repeated until all balls are depleted.

Presenting someone with facts that contradict their perceived view of the world often results in the "backfire effect" Rather than admit they're wrong, they invest greater belief in their unreliable information #psychology

"The older I get the more I realize how being grateful for simple things make life beautiful: a cup of coffee, a smile on children's faces, clean laundry, waking up in the morning and just being in the here and now, not trying to figure out the whole life at once. The older I get the more I realize how all the messiness in life taught me the most important lessons in appreciation and gratitude, and shaped me into a stronger, beautiful, perfectly imperfect person. The older I get the more I realize that each day is a new beginning and that I have the power and right to choose my battles and attitude, even when I can't change the circumstances."✨ Jelena Rakic #quotes

​​How Does a Fuel Level Sensor Work? Fuel level sensors, also known as fuel gauges, allow drivers to monitor fuel consumption and help them to determine when to refill the tank. They consist of two main components: the sensing system itself (also known as the sender) and the indicator (also commonly referred to as the gauge). The sensing system is located in the fuel tank and consists of a float usually made of foam and connected to an actuating metal rod, attached to a variable resistor. The variable resistors used in fuel levels sensors are often composed of a resistive material, where one end is attached to the ground, with a wiper (much like a very small windscreen wiper) that moves over the resistive material as the float moves. When the float moves due to changing fuel levels, the wiper moves across the resistor, causing a change in voltage. The orientation of the wiper means that the highest resistance is experienced across the resistor when the tank is empty. At this point, the wiper is also as far away as possible from the ground end of the resistor. The change in current is then passed on to the indicator which in turn changes the reading. However, fuel level sensors in automobiles can often be inaccurate, especially when driving with a full tank. In this scenario, the float will rise to the top of the tank, with the wiper returning to the ground end of the resistor, resulting in a small resistance and a high current passing through the sensor. As the float drops in height, the resistance changes; but the gauge will often remain on 'full' for some time. This is because when the fuel tank is full, the float cannot position itself on top of the fuel, as it is blocked by the tank or is limited by the reach of the actuating rod attached to it; meaning that the float becomes submerged when the tank is full. This leads to inaccurate readings until the fuel drops to a level where the float can sit on top, allowing the resistance to change. Similarly, when fuel is low, the rod often does not extend to the end of the tank, causing the gauge to indicate an empty tank when actually some fuel remains.

​​What Is the Difference Between Good and Bad Cholesterol? Cholesterol, a waxy substance that builds in the arteries is not completely harmful, despite its reputation for being bad for you. In fact, some of it can even improve your health when consumed in the right amounts. There are two types: high-density lipoprotein (HDL) and low-density lipoprotein (LDL). As a general rule, HDL is considered “good” cholesterol, while LDL is considered “bad.” This is because HDL carries cholesterol to your liver, where it can be removed from your bloodstream before it builds up in your arteries. LDL, on the other hand, takes cholesterol directly to your arteries. This can result in atherosclerosis, a plaque buildup that can even cause heart attack and stroke. Triglycerides make up the third component of cholesterol and act as unused calories that are stored as fat in the blood. Eating more calories than you burn can cause triglycerides to build up in the bloodstream, increasing your risk for heart attacks. An LDL count of 100 or less is considered healthy. Your HDL count should be at least 40 (or 50 if you’re female) or greater. Healthy triglyceride counts are 150 or less. Your “numbers,” or total HDL and LDL cholesterol plus triglycerides, should add up to no more than 200. If your numbers are higher than 200, check with your physician, you may have a higher HDL count, which is not unhealthy. Maintaining healthy levels of cholesterol is manageable. Medication is key, along with eating a healthy diet with lots of vegetables and getting regular exercise.
