Macro to nano universe - An incredible experience

This presentation explains the macro universe and the universe which is underlying in the lower dimension

1. Macro Universe to Nano Universe Dr.A.Nichelson Assistant Professor of Physics National Engineering College K.R.Nagar , Kovilpatti-628 503

2. What is Physics??

3. The size that is matter !!! Size of object or distance Length (m) Size of proton 10 -15 0.000000000000001 Size of atomic nucleus 10 -14 0.00000000000001 Length of typical virus 10 -8 0.00000001 Wavelength of light 10 -7 0.0000001 Thickness of paper 10 -4 0.0001 Height of Mount Everest above sea level 10 4 10000 Radius of earth 10 7 10000000 Distance of moon from earth 10 8 100000000 Distance of sun from earth 10 11 100000000000 Distance of pluto from sun 10 13 10000000000000 Size of our galaxy 10 21 1000000000000000000000 Distance to Andromeda Galaxy 10 22 10000000000000000000000 Distance to observable universe boundaries 10 26 100000000000000000000000000

4. Theories of Universe Big bang Holographic Universe Parallel Universe Multiverse Simulation Reverse Universe……..!!!!

5. String theory of universe

6. Hide Newton when he is in an open ground without any obstacles?

7. 1N/m 2 = 1pascal 1m 1m 1m 1m

8. The tiny universe…. Microscopic world Nanoscience Nanotechnology Quantum Computing Richard Feynmann Size of an atom??? Size of a nucleus?? Spin of electron If you think you understand quantum mechanics, then you don't understand quantum mechanics There is plenty of room at the bottom

9. Wave or Particle?

10. History timeline 2000 Yr Ago Sulfide nanocrystals used by Greeks and Romans to dye hair 9 th -century Glittering effects of pots using nanoparticles by Mesopotamians 1000 Yr Ago Gold nanoparticles of different sizes were used to produce different colors in stained glass windows. 1959 Richard Feynman’s speech - “There’s plenty of room at the bottom” 1974 First Molecular Electronic Device patent. 1981 IBM Invents scanning probe microscope 1985 Curl, Kroto , Smalley discovered Buckey balls the ‘fullerenes’ 1989 IBM Almaden Research Center: wrote IBM with 35 Xenon atoms . 1991 Discovery of carbon nanotubes

11. Surface area to volume ratio

12. Surface to volume ratio…..!!! Size of cube side No. of cubes Collective Surface area 1 m 1 6x1x1 6 m 2 0.1 m 1000 6x0.1x0.1x1000 60 m 2 0.01 m 10 6 6x0.01x0.01x10 6 600 m 2 0.001 m 10 9 6x0.001x0.001x10 9 6000 m 2 10 -9 m 1027 6x10 -9 x10 -9 x10 27 6,000,000,000 m 2

13. Hydrophobic…..???

14. Evolution of transistors….

15. What is this?

16. What will happen when you join two ice cubes?

17. How does it happen…??

18. A device….???

19. A famous personality who inspired many youngsters

20. The man who made us connected

21. Physics terminology

22. What is the similarity between them??

23. Explore the world “Identity losses when we cross the boundary” Where are you from? What is your answer to this question, when you are in Another City Another state Another country Another universe What do you say when you meet an alien?

24. Career opportunities in physics NET/SET/JRF CSIR labs, BARC, KKNPP TET/TRB ISRO IIT/NIT

25. Build your own universe Choose the right specialization which is of your interest Learn programming – C language Do projects Publish Youtube channel Use social media Self-promotion Blogs Competitive exams!
