Physics is an indivisible part of human being's life.

We are seeing it but never notice physics and the role of it's concepts such as quantum mechanics and light in planting and agriculture,medical aims.

Physics is physics.

Physicists are not engineer and they always try to study on green .topics to serve the community and human biengs 

Physics and people Ehsan Tanhaee's scientific contributions

Physics is all around us, even in things we use every day without realizing it. Here are some examples of everyday items where physics plays a role:

Clocks: Clocks rely on the physics of pendulums or oscillators to keep time accurately.

Mobile Phones: Physics principles are used in mobile phones for wireless communication and data transmission through  waves.

Eyeglasses: Optics is essential in designing eyeglasses to correct vision problems by manipulating light.

Refrigerators: The cooling process in refrigerators is based on the physics of thermodynamics and heat transfer.

Radios and TVs: These devices work by utilizing the physics of electromagnetic waves to transmit and receive signals for broadcasting.

GPS Navigation: The Global Positioning System (GPS) relies on the physics of satellite communication and precise timing.

Speakers and Headphones: Physics is involved in the conversion of electrical signals into sound waves that we hear through speakers and headphones.

Cameras: Cameras use optics and the physics of light to capture images by focusing light onto a sensor or film.

Musical Instruments: Musical instruments, such as guitars or pianos, rely on the physics of sound waves and vibrations to produce music.

Cars: Physics is involved in the design and operation of cars, including the mechanics of engines, the movement of vehicle bodies, and the physics of friction in tires.

These are just a few examples of how physics is present in everyday items and activities. Understanding the underlying physics can help us appreciate the science behind these objects and how they enhance our lives.

Physics helps us understand how things work in the world around us. It has practical applications that can affect our daily lives and expenses. Here are a few examples:

1.Physics helps us find ways to use renewable energy sources like the sun and wind, which can be better for the environment and potentially lower costs. It also guides the design of energy-efficient appliances, such as LED lights and hybrid cars, which can help us save money on electricity and fuel.

2. This is about how things move and the forces that affect them. Understanding mechanics can help us design vehicles that use less fuel, which can save us money at the gas station. It also helps engineers build strong and safe structures, which can impact construction and maintenance costs.

3: This is about how heat, temperature, and energy are related. By understanding thermodynamics, we can design better heating and cooling systems for our homes, which can make them more comfortable and reduce energy costs. It also plays a role in refrigeration technology, which affects food preservation and energy usage.

4: Optics is about how light behaves. It helps in making better cameras, telescopes, and microscopes, which can improve medical imaging and scientific research. It's also used in fiber optics, which enables high-speed internet, potentially lowering communication costs.

By understanding these physics concepts, we can make informed decisions about energy use, technology choices, and resource management. This can potentially lead to lower living costs, increased efficiency, and a more sustainable lifestyle.

Ehsan Tanhaee: teaching Polariton as a general mass in physics

Polaritons: Shining a Light on the  Relationship Between Light and Matter.

Polaritons are usual particles that form when light interacts with substances. They allow scientists to study how light and matter can come together in some ways.

While polaritons may sound , their study has practical applications that impact our daily lives. Here are a few examples:

Energy-Efficient Lighting: Scientists use polaritons to make LED bulbs. These bulbs produce bright and long-lasting light while using less electricity, helping us reduce energy consumption in our homes and workplaces.

Faster acts in cellephones: Polaritons contribute to the advancement of electronic devices we use every day, such as smartphones and computers. By studying polaritons, scientists can make electronics faster, more powerful, and more efficient, leading to improved devices and faster communication.

Materials: The study of polaritons helps scientists discover and understand new materials with unique properties. These materials can be used in various applications, from renewable energy technologies to medical devices, bringing advancements that improve our lives.

While you may not directly interact with polaritons in your daily life, they are the building blocks for technologies and tools that we commonly use. For :

LED Lights: LED bulbs, which are more energy-efficient and longer-lasting than traditional incandescent bulbs, rely on the principles of polaritons.

Smartphones and Computers: The faster processing speeds and advanced capabilities of our smartphones and computers are made possible in part due to the understanding of polaritons and their impact on electronic devices.

In summary, polaritons are particles that help scientists understand the relationship between light and matter. This understanding leads to advancements in  lightingThese advancements, in turn, impact our lives through everyday tools like LED lights, smartphones, computers, and even renewable energy.

Ehsan Tanhaee: physics teaching for students and Nano science

Physics Teaching for Students and Nanoscience: Discovering the Secrets of the Universe and the Tiny World of Nanotechnology

Physics Teaching for Students: Physics is the study of how things work in our world. When students learn physics, they discover the basic rules that govern everything around us. They learn about motion (like how objects move), forces (like pushes and pulls), energy (how things have power), and electricity (how we use it for various purposes). Through fun experiments and explanations, students explore the fascinating ways physics impacts their everyday lives.

Nanoscience: Nanoscience explores the incredibly small world of tiny particles that are thousands of times smaller than a strand of hair. Scientists use nanotechnology to study and manipulate these tiny particles. This field has amazing applications in many areas, such as medicine, electronics, and energy. It opens up possibilities for creating new materials, improving technology, and finding solutions to important problems we face. Nanoscience shows us how even the tiniest things can have a big impact!

By teaching physics to students and introducing them to nanoscience, we help them understand the world around them and inspire them to explore the wonders of science. They learn about the laws that govern our universe and get a glimpse into the exciting world of nanotechnology. These educational experiences nurture curiosity and can spark an interest in scientific careers and innovation.
