In summary, physicists can do a lot to help solve world problems, but they may not be the best people to do it because politics can get messy.

I know a lot of the technology (if not all) draws back to physics but what can physicists do to solve world problems and issues?

A short and blunt example:

Biology and medicine depend on chemistry to a certain degree.
Chemistry depends on physics.

I took chemistry and physics and have seen where they interlock but what can a physicist discover that can solve a problem like a disease or global warming etc.

MRI, CT scan, semiconductors, ICs, computers, mobile phones, radio, wifi, websites, digital cameras, satellites, nuclear medicine, medical imaging, biological imaging, and all of the uses of these things.

Plus our sexiness.

Michael Faraday was once asked by one of the British ministers at the time: "What was the use of the law of electromagnetic induction he had discovered?" He replied: "I don't know, but some day you tax it". Speaking of technology that is used to produce most of electrical energy we use today.

I am believe that any discovery finds an application sooner or later though it is not at all simple (impossible?) to see one when the discovery is made. The question is would we live long enough to see it applied?

There are two things that I see as helping the world and society.
1. Pursuing understanding for it's own sake, and asking what we can give to nature and the world because of it. Too much progress is centered on how we can reverse engineer nature and then make some bank. That seems to me to be the wrong direction.
2. Contribute more to the image of humanitarian scientists. The innocence of science and wonder and asking questions gets a bad rep. and then people in other public roles, or just non-scientists don't want to fund research and the portion of resources given to science is diminished. At least people like some of the giants in science.

If physicists really want to make the world a better place, they should get involved in politics.

Err, no they shouldn't. Politicizing science is an awful idea. Can you imagine the acrimony in a string party vs loop party campaign?

They can stop doing physics, that will save more lives than keep doing physics. :-D

Can you explain why you'd think such a thing?

What if we stopped doing physics 500 ears ago?Our lives would be miserable.Try to imagine,Someone from another universe whose technology is so great came to our world and started showing off.How jealous would we be.We would be living in caves if we had stopped doing physics.

That is not as nasty as the Emergent Party versus the Reductionism Party! The Reductionism Party still hasn't forgiven the Emergent Party for helping to kill the SSC!

:)

Zz.

We can't stop doing physics, it's against our biological makeup to. As humans we're always going to question and experiment whether you like it or not.

I agree.

The first person who, having dropped a rock to the ground, bethought himself of saying "This is weird, but I have an idea how this works", and found people simple enough to believe him, was the real founder of physics.

Yes, I did a shameless theft and rewrite of this Rousseau quote.

Atom bombs, nuclear waste, environment contamination... and the list goes on.

You compare your life today with back then, but I don't think that people back then were any more miserable than people today. You just get accustomed to whatever technology you have.

Physics has taught us to question and not just believe what is told to us, with physics comes questioning which comes revolution.

Ignorance leads to superstition, which in turn leads to oppression.

Physics, at its core, illuminates our understanding of the world around us.

Learning is how we grow.

You are right but people back then might have thought that they were full of technologies(Eg :fire)that would eventually destroy them but fire is a necessary evil.Likewise,Nuclear technology is also a necessary evil.Think about advantages of nuclear power stations

Everything has advantages and disadvantages, that's granted.

I don't think that physics can make things better, people can do it regardless of physics.

Physics is what will make clean and efficient energy technologies viable and cheap enough to be used more widely. They're working on different photoelectric technologies to make solar panels cheaper to manufacture. But it's not just limited to solar power, either.

In the (possibly near) future, physics will perfect the various technologies that will give us quantum computing, which is so much more powerful than classical computing that it could more accurately simulate biological systems, so physics will directly lead to various cures.

Not to politicize science, to bring scientific values and thinking to politics.

Ignorance leads to Fear, and as we all know, “Fear is the path to the Dark Side. Fear leads to anger. Anger leads to hate. Hate leads to suffering.” :biggrin:

Therefore, physics helps prevent worldwide suffering.

1. How can physicists use their knowledge to improve renewable energy sources?

Physicists play a crucial role in developing and improving renewable energy sources such as solar, wind, and hydro power. They use their knowledge of energy and thermodynamics to design more efficient systems and find ways to store and distribute energy more effectively. By continuing to research and innovate in this field, physicists can help make the world a cleaner and more sustainable place.

2. What impact can physicists have on healthcare?

Physicists are involved in a wide range of healthcare advancements, from developing new medical imaging technologies to improving radiation therapy for cancer treatment. They also research and develop new materials and devices for medical use, such as prosthetics and implants. By leveraging their understanding of physics, physicists can make significant contributions to improving healthcare and saving lives.

3. How can physicists help address climate change?

Climate change is a pressing issue facing the world today, and physicists have a crucial role to play in finding solutions. They can use their expertise in areas such as atmospheric physics and climate modeling to better understand the causes and effects of climate change. Additionally, physicists are working on developing new technologies for clean energy and reducing carbon emissions to combat the effects of climate change.

4. In what ways can physicists contribute to space exploration?

Space exploration is a field that heavily relies on the principles of physics. Physicists are involved in designing and testing spacecraft, developing propulsion systems, and creating technologies to support astronauts in space. By pushing the boundaries of our understanding of the universe, physicists are also helping us gain a better understanding of our place in it.

5. How can physicists make transportation more efficient and sustainable?

Transportation is a significant contributor to air pollution and greenhouse gas emissions. Physicists are working on developing more efficient and sustainable methods of transportation, such as electric vehicles and alternative fuels. They also use their knowledge of fluid dynamics and aerodynamics to improve the design of vehicles, making them more streamlined and fuel-efficient. By applying their expertise, physicists can help reduce the environmental impact of transportation and make it more sustainable for the future.
