Everyone makes predictions. We predict the traffic on our roads; we predict the amount of money something might cost among other things. Sometimes we are right and sometimes we are wrong. Physics as science involves a lot of calculations. It involves picking out various mechanisms in the universe, figuring out how they work and work out the equation in order to describe it. This is a way of predicting the future. We want to be able to know what to expect from the world so that we can know how to move or be prepared. Physics is one of those sciences that can predict the future to some extent. Below are some various instances that prove physics can predict the future.
Laws of motion
We all have control of movement. We plan that we shall either move forward or whichever direction that we purpose to go. This is a bit hard to predict. However, when it comes to things that we have no control of, we can predict their movement. It cannot be really used to predict the future as some phenomena are a bit too complex. What we can do is use the knowledge and use it to our advantage. For instance, the force of gravity. When boarding a vehicle especially public means such as a bus, passengers are always told to maintain a sitting position all through so as to maintain the centre of gravity.
Is more people are standing compared to those seated, the centre of gravity will be upset and this leads to an imbalance. The bus will, therefore, be at risk of toppling over or being involved in an accident. Having this knowledge helps us know how to behave in such situations and what to avoid in such situations.
2- Moore’s law
This law mostly has to do with the computers that most of us make use of every day in our lives. The assumption or rather the prediction says that a computer’s processor increases its speed every two years. We, therefore, have to prepare ourselves every two years to accept the new changes and adapt fully so as to be in line. Actions around us that we may have been doing may also be affected and may also need changes. The problem, however, comes once we take another angle at this law. If engineers who come up with these processors decided to stop working and not make any improvements, these assumptions would automatically be invalidated. We cannot expect a change every two years if no one is there to spearhead these changes.
By observing the weather, physicists are able to anticipate natural disasters such as tsunamis and earthquakes. Such information is very helpful as it will help people stay safe. If people are able to know when a disaster is expected, they will be able to move to safe houses and take all necessary measures to minimize damage. The weather, on the other hand, helps farmers predict the economic situation and help the government prevent or stay on top of any looming economic crises. On the downside, incorrect predictions can be very harmful to a country as measures to counter the problem may be too harsh hence end up doing more harm than good.
