Problem: Article: Use a staple puller or flathead screwdriver to remove the staples from the ends of the rails. Cut the old felt along the top of the rail if it does not come off immediately. Each rail has a thin wooden "featherstrip" running alongside it, which is typically not attached by any adhesive or nails. If it won't come up easily, Use a thin flathead screwdriver to pry it up without breaking it. Unlike the table top, this felt should be "face side" down. Keep an overhang of at least 4 inches (10 cm) on each end, and 1/2 inch (1.25 cm) over the feather strip groove. Lay the featherstrip back in position, but do not press it down. Have an assistant stretch the felt tightly between the center and one end of the railing. Place a tapping block over the featherstrip, then use a hammer to gently tap the block, pushing the featherstrip down into the stretched portion of the felt, but stop about 2 inches (5 cm) from the end, where the corner pocket will be located. Stretch the other half of the felt, and repeat this process for the remaining length of the featherstrip, again stopping 2 inches (5 cm) away from the other end. Do not strike the featherstrip directly, or you may dent the table. Pull the felt at the ends of the table toward the rubber cushion, then tap in the remaining portion of the featherstrip until it is firmly in place. Trim and fold the felt as necessary to remove excess material and cover the ends of the cushion. Once all your rails are complete, bolt them to the table again. If you're having a hard time finding where the bolts should go, you can push a screwdriver through the bolt holes as guidance. Never try to cut holes in the playing surface from the top of the table, as you may cut in the wrong place.
Summary: Remove old felt from rails. Gently remove the wooden feather strip. Place a new strip of felt over the rail. Use a tapping block and hammer to wedge in the center of the featherstrip. Pull felt toward the cushion and tap in the ends of featherstrip. Reassemble the outer rails.

Problem: Article: Stir the nigari into a cup with a few tablespoons of water. Keep stirring until the coagulant has completely dissolved. Turn the heat to medium and let the water come to a steady simmer. Simmer the tofu for about 10 minutes, or until the tofu is just set, like a quiche or custard. You can serve it warm or chill it in the refrigerator for later. Popular toppings include lemon zest, shaved cucumber, sea salt, bonito flakes, grated ginger, and soy sauce.
Summary: Make a coagulant solution. Simmer the tofu. Serve the tofu.

Problem: Article: First, you need to answer some basic questions: what makes your product, company, or idea great? If you've been in development for a while, you likely have a short description of what's good about your product already. But what makes it unique? What problem does it solve? If you have been in development, you should already have an idea of who your audience is. However, if you still aren't sure, you can run tests on groups of people to see who connects with your product. Invite people to try it out, then ask them to answer a few short survey questions to determine demographics and how well they liked your product. If you've figured out what makes your product unique, try to figure out how to transfer that uniqueness into the format you plan on using. Some explainer videos use a white board, chalk board, or a piece of paper with someone drawing out the explanation as a voice narrates. Some use animation. Many use humor. Decide on a unique approach for your video.
Summary: Address the basic questions. Determine your audience. Think about ways you can present your idea uniquely.

Problem: Article: What is the objective of creating a model? Make a list of the data you want to find by using the model. It is crucial to ask this question before you create your model or you may end up creating a model that does not meet your objective. Do you want to predict something? Find out how to regulate something? Or do something else? For example, imagine you want to know how much room you have in a storage unit to see how many boxes you can put into it. You will be creating a model to predict the amount of space that is in your storage unit. What data do you already have? Make a list of the data that has been given. As you list the data, decide what pieces are most relevant and which pieces are not relevant. You should also list any information that can be assumed based on what you already know. Keep in mind that you may have to take measurements to find the data that you need. To find out how much room you have in your storage unit, you will need to measure the unit's height, width, and length. Do you need to consider factors like gravity, volume, time, etc.? Make a note of any factors that will need to be considered when you create the model. To determine the amount of space that you have in your storage unit, you will need to find the volume. You also need to keep in mind that there will be some wasted space, since some objects may be irregular and that will make it difficult to use every inch of the storage unit. What equations and formulas will you need in order to find your answer? How will you apply these equations and formulas? Make sure that you have a clear understanding of how to plug the data that you have into the equation. To find the volume of the storage unit, you will need to use the equation V= h x w x l There is no need to re-invent the wheel if somebody else has developed a model that may suit your purposes already. Check in your textbook or ask your teacher. Just remember to make sure that someone else's model will work for your situation. To get an idea of how to find the volume using the equation you have identified, check your textbook or ask your teacher. A simple mathematical model may not require a diagram. However, if you are creating a complex model, a diagram may help you determine if your model will work. Draw a diagram to represent the actual model you plan to make. Make sure to incorporate your data into your diagram to help guide you when you create the actual model.
Summary:
Determine what you want to know. Determine what you already know. Determine the physical principles that govern the model you want to create. Identify the equations that you will need to use to find your answer. Look at what others have done. Create a diagram for your model.
