The famous physics experience shows the reason for the government’s “useless” flag support

It creates the lighter weight of a small spark that jumps from wire to the other in the front pair. This spark creates electromagnetic waves, with wires as transmission antennas for amplification of waves. The two walkers are the receiving antennas, and they will produce an electrical current, as with the wire loop in Hurtz. Instead of creating a spark on the reception device, on my device, the light bulb will run. The neon bulb is really nice because it is highly voltage but low trading, and this is exactly what we need.

Ok, the lights are extinguishing! Here’s what it looks when you shoot this spark.

It may seem trivial, but it is not. You are actually sending and Receive electromagnetic waves.

Knowledge, what is good?

When Hertz showed his experimental investigation of Maxwell’s equations, the science community knew it was great, and the general public was curious. Journalists, of course – in any case – give it the pragmatists – what can be used for it. Response:

“There is no use in anything … This is just an experience that proves that Maestro Maxwell was right – we just have these mysterious electromagnetic waves that we cannot see with the naked eye. But it is there.”

Why are you getting lost on experiences if they are not useful? Well, the sincere truth is, this is not the reason we do science. Human nature makes us explorers. We ask questions and search for answers. It is just one of the things that makes us. Sometimes the answers are wrong (it turns out that the sun does no Crossing the sky in a vehicle drawn by white horses), but we are always looking for the best.

Sometimes science is wrongly useful. In fact, the results of the Hertz experience are likely to use now. Not only did Maxwell’s equations were legitimate, as he actually invented the first radio transmitter. (Radio waves are just a slice of electromagnetic spectrum.) Then this was used for wireless microorology that allowed people to communicate with ships in the sea using a Morse icon. After that, people discovered how to send music and soap via opera and commercial ads via radio waves, so we only call it “radio”. There was also this thing that is called TV can broadcast moving images across space.

But it does not stop there! Since the device sends the electromagnetic waves that reflect objects, you can measure the time it takes to return to the return, which tells you to what extent they are away from the INE, Radar and Lidar, which are used in self-driving cars. Of course, the transmission of cell phone, Wi-Fi, and Bluetooth are all electromagnetic waves. It is literally everywhere – swimming in a sea of ​​electromagnetic waves.

So if the United States spends money on science, will it enhance profits and economic growth? Sometimes yes, sometimes no. There are many great discoveries without real application. I mean, look at the gravitational waves discovered from the collision of black holes. Will this lead to a new type of internet or something like that? Maybe not. But we are definitely richer to know that.
