I recently bought some light bulbs for replacement and noticed that we still have some old fluorescent bulbs and a few incandescent bulbs at home. Both of these types generate heat and can get very hot when being replaced. In contrast, LED bulbs don't get nearly as hot during replacement, and they provide strong light without consuming much electricity. I believe this is a major advancement in human technology. In every aspect, LED lighting surpasses older lighting technologies. Nowadays, much of the lighting in our lives relies on LEDs. The breakthrough that led to the successful commercialization and mass production of LED bulbs was even awarded a Nobel Prize. Therefore, I believe this achievement deserves to be commemorated.

The astrolabe is a historical measurement instrument used in astronomical observations. Its applications include determining the positions of the Sun, Moon, planets, and stars. Additionally, it was used to calculate the local time and prayer times in Islam. The astrolabe was also employed in solving certain mathematical problems. Western sources report that it was first discovered by Apollonius (240 BC) and Hipparchus (150 BC), used by Ptolemy, and mentioned by Philoponus in the first half of the sixth century. In the 9th century, at the great university in Harran, various works about the astrolabe were written, thanks to the Abbasid caliphs' emphasis on science and culture. The oldest known book on the subject was written by Ali ibn Isa, who worked in Baghdad in 829–830 and in Damascus in 833. According to another account, the first person to discover the astrolabe was Abu al-Qasim Hibatullah, who was appointed by Seljuk Sultan Masud to the Baghdad Observatory and was known by the title Badi' al-Usturlabi ("Master of the Astrolabe"). Sultan Masud completed the Zij (astronomical tables) he prepared under this title in 1130.

Thanks to the privileged skies of the Elqui Valley in the north of the country, Chile has the most advanced astronomical observatories on the planet.

The first successful heart transplant was performed by Dr Chris Barnard in Cape Town on 3 December 1967. Louis Washkansky was suffering from heart failure and Dr Barnard decided to take a chance and operate. Dr Barnard went on to perform at least 10 more heart transplants and paved the way for improvements in this medical field.

Italy except for its beautiful language, a lot of unesco sites and delicious food is also known for its cars. It would be nice to have a stamp set with the Italian cars: Fiat, Ferrari, Lamborghini, Alfa Romeo, Maserati

Astrophysics stands above politics and wars. Scientists and astronauts continue to do science work on the space station. I would like to propose to make a stamp with the image of Yuri Gagarin, the man who first flew into space, as a symbol of both the Russian space program and a significant contribution to world space exploration. Astronauts are the heroes of our time, about whom people speak too little. Yuri Gagarin was born March 9, 1934.

A stamp of the Chinese space station could be made, add elements of the launch vehicle and several lab modules.

Dear Slowly Team, Today is the International Day of Women and Girls in Science — February 11. I would like to take a moment to celebrate this meaningful day and express my gratitude for creating such a wonderful platform. Empowering women and girls in science and technology is truly invaluable. Perhaps next year, you could consider creating a special stamp to honor this important day? It would mean a lot to us. Thank you for your continuous efforts and creativity. Warm regards
