The Great Physicist Marie Curie

Radioactivity is used commonly in our daily life now. From medical purposes such as cancer treatment to nuclear reactors, radioactivity solved much of human's problems and desire. However, the scientist that discovered radioactivity is not Einstein or Newton. Instead, it is a female physicist, named Marie Curie.

Marie Curie's discovery had made a significant impact in the science and medical field of human's endeavour. One of the significant impact from the discovery of radioactivity is the use of radiation for cancer treatment. It is found that radioactivity kills disease cells and tumour without harming the healthy cells. This is a breakthrough in the medical field as a cure was found for cancer, an illness that people seen as incurable. Not only that, the patients had also given another chance to live with the invention of this treatment. Presently, doctors around the globe is using this treatment as one of the treatment to cure cancer.

Besides using radioactivity for medical purposes, the founding of radium also lead to nuclear reactors. Electricity is generated using nuclear energy, benefiting the human community. For example, nuclear energy is used in various countries like Canada and USA. The use of nuclear energy helps to save the consumtion of fossil fuels, which can be used to produce liquid fuel.

Lastly, the discovery of radium led to the discovery of electrons, protons and neutrons in atoms. The discovery of atoms let us know more about chemistry. This is also an significant impact on the science field as sceintist were motivated to investigate more about atoms. Nevertheless, the influence of this discovery persist till today as students around the globe were taught to study regarding atoms and their characteristics in chemistry.

The discovery of radioactivity is the most significant contribution by Marie Curie to the world. The impact of this discovery is still felt by the human community today. Hence, Marie Curie is definitely one of the most influential people who had played a significant role in the modernisation of human community.

self introduction!!!

Hi all! I am Lim Yi Jia from 08/07! This is a brief self-introduction of mine, and to speak the truth,I don't really like to have a blog. =x I used to create one but after a few posting, i deleted my account! I don't have the habit of writing dairy u see.

Well, let me start by telling you a little about where i came from. My previous secondary is Kranji Secondary and i joined ELDDS during my secodary school times. This year, i joined the Chinese Ochestra in AJC and the instrument I play is Er Hu. I know it seems that only old man would want to choose this instrument but i truly have a great interest in it! (Could it be I'm old at heart???!!!) I've attended two sessions of practices this week and i really had a great time learning the Er Hu from my seniors!

Besides having an interest in Er Hu, I'm a fan of manga and animes! What drew my attention are the drawngs of the mangas and animes. Though I do not have the skills of Da vin ci, i will still try to draw some characters from the mangas.(Sadly, they drawings aren't goodT.T)

Among all the animes that I'd watched, my favourite is Full Metal Alchemist. The story of this anime is not as cheerful and optimistic like other animes like One Piece. Instead, it is full of provocative questions and sentences that makes you think deeper about what we may never notice in life. I enjoy thinking about these questions as you may find a totally different view to things.

Lastly, i shall share a little on my character. Actually, I'm an introvert. Though I am able to make new friends and fit in comfortably in a new environment, having personal time with myself is very important to me. I like to spend the time alone as it clears one mind and is the best time for some introspection. So if anyone interups me durig this time I'lll most probably be very annoyed with them and ask them to LEAVE!! WAHAHAHHA!!

Hope you enjoy reading my first entry!!
