Beauty of science through microscopes

Very well, and today we are going to discuss on the most important 'weapon' in science which is the microscope. Microscope is a device that can lead us to a new mini-micro world of organisms. And do you know what we are made from small tiny little cells to form tissue, organ and system? Antonie Philips van Leeuwenhoek was a Dutch tradesman and scientist from Delft,Netherlands. He is commonly known as "the Father of Microbiology", and considered to be the first microbiologist. He is best known for his work on the improvement of the microscope and for his contributions towards the establishment of microbiology. Using his handcrafted microscopes, he was the first to observe and describe single celled organisms, which he originally referred to as animalcules, and which we now refer to as micro-organisms. He was also the first to record microscopic observations of musclefibers, bacteriaspermatozoa and blood flow in capillaries (small blood vessels). 


This is the first microscope he invented. Looks simple, but it can function very well to look at microorganisms. 

 See, there are so many different types of microscope invented by some really great scientist. How microscope works? It mainly based on light and lens. 

And today in this modern world, all the educations institutes like schools are provided with microscopes for the students to explore. 


Teachers and educators should demonstrate the correct method in using microscopes and encourage the students to use it or a right purpose. 
Science is just so beautiful, isn't it? =D

Robots

Hello everyone! =D
I'm very sure in this modern, globalized and technological world, you've heard of "robot". And today we are going to talk about robots. Robot is a  machine capable of carrying out a complex series of actions automatically, and also a machine resembling a human being and able to replicate certain human movements and functions. In other words, robots are very good helpers to us human being. 

There are so many different types of robots that can help us human being in our daily work and activities, especially jobs that are difficult, dangerous or dull. They lift heavy objects, paint, handle chemicals, and perform assembly work. They perform the same job hour after hour, day after day with precision. They don't get tired and they don't make errors associated with fatigue and so are ideally suited to performing repetitive tasks. 


Industrial RobotOne of the example will be industrial robots. Industrial robots are found in a variety of locations including the automobile and manufacturing industries. Robots cut and shape fabricated parts, assemble machinery and inspect manufactured parts. Some types of jobs robots do: load bricks, die cast, drill, fasten, forge, make glass, grind, heat treat, load/unload machines, machine parts, handle parts, measure, monitor radiation, run nuts, sort parts, clean parts, profile objects, perform quality control, rivet, sand blast, change tools and weld.



As you can see, robots can help us in activities that is dangerous for us to do it. Not only that, there are some robots that are very entertaining. They can dance, play music, sing song, do whatever activities you wish to. It is so amazing! Don't you think so? 

Look at this, it's a dancing and singing robot. She looks like real human don't she? =)

I strongly believe that science will make a country more advanced. Therefore, the generations nowadays should take the opportunity to learn new technologies and apply it in our country. We will have a better tomorrow and better day. =)
