Forensic Science? I Doubt It!

Hey yo to this world of renowned scientist again! Today, we have nothing to entertain you except for forensic science! I am sure you guys know what that is. Well, if you have no idea, it is using the science of clues and traces to solve a mystery, like solving a crime case you could said. Well, we learnt this last year but I guess I want to talk about it today. Many scientists are needed for this tedious task. It is said that forensic science is unbeatable as the criminals always left some traces of theirs behind. But here I am to prove you wrong. Well, I am not sure whether it is true but I seem to have some tingling feeling in my mind that tells me there are still flaws in the work of forensic science. So, let’s get started shall we?

Alright, we all knew forensic science mainly uses clues and traces left behind. Things like fingerprints, DNAs and stuff like that. They said fingerprints are superb for identifying suspects but have you ever wondered that fingerprints can be forged? Literally! If you have watched a show called "Mythbusters" you might understand what I meant.

The thing to defeat fingerprints is for the criminal to wear gloves, and if that does not help much, there is always the work of using other people’s fingerprints. How do you do that? Well, first of all you will need some fingerprints(obviously not your own). Brush them out(that’s what the police anyway). Use a kind of material(I have forgotten what it is called) and pour(in liquid form, thats what) them over the prints. The material will dry and harden and now all you have to do is to cut the prints out and put each print on each of you finger. As you see, when you brush out the original fingerprints, it leaves some layer of that print of the surface and when the material is poured over it, it takes the shape of the layer. When it dries, the prints will be forged onto the material itself. It sure works for fingerprint scanners too. So the fact of fingerprinting is always successful is BUSTED.

And now, DNAs. They mainly look for blood and stuff like that which will match the DNA of the suspects. But just imagine, if the criminal were to be in some sort of suit that prevents any bits of him containing his DNA from being left behind, how are they gonna find out? That includes some sort of helmet to prevent any loss of hair at the scene. With this, DNA has been defeated since there is nothing of the criminal being lost and left behind for the scientist ti find out.

And of course, they like to look at foot prints eh? Well, let’s just imagine the soles of the criminal’s shoes have been covered with a layer of material, a bit like rubber. Now, how are they gonna find out? Besides, I wondered how the investigators managed to find out the suspect’s identity merely just by looking at footprints. Do they already have a copy of his footprints before? And if so, wouldn’t the criminal be clever enough to change his shoes? This is getting utterly ridiculous! People getting answers just by looking at something they do not know!

Footprints, fingerprints and stuff like that are getting useless in the help of investigations since they can be easily forged nowadays and even eye-scanners are becoming a laughing stock. This new world of criminals are getting smart and they are smarter than the best detectives and even Sherlock Holmes, though he is just a fictional character. So let me ask you this question: Is forensic science really unbeatable? The answer is: NO!!! I don’t believe there is something so powerful it is never defeated in this world.

Time Is Terrific!!

Hello again to the world of renowned scienctists. Fancy having more scientific knowledge? Then this blog is for you! Now, the topic. Have you guys ever think about time? No? Then you guys are totally taking things for granted! Time is a complicated thing to study. The most famous person for this job is……Albert Einstein! The renowned scientist(who likes to stick his tongue out) is the first to define time. He says time and space are the same thing and came up with a complicated formula that even now, there are still scientists who don’t understand it. So, what is time? Time is the chronological interval between events measurable by atomic oscillation. Um… pardon me if you don’t understand. Neither do I. Mind you, you need a brain as big as an elephant’s to understand that! Oh, here’s Albert Einstein:


Now, let’s move on. Before time, there was nothing. Absolutely nothing. Not even a speck of atom. Then an explosion occured. It is called the Big Bang and marks the start of time. It is the Big Bang that creates the Universe. Without it, I wouldn’t even be here typing! Space and time are related in some ways. Just imagine time and space as a straightened out carpet that is floating in the air(like the flying magic carpet from "Aladin".) You see, each object in space has mass. The more the mass, the more its pull of gravity. Now, just imagine some balls of different size were put onto the carpet. The one with the most massTim will ‘attract’ the other balls towards it. That is, the smaller balls will gather around the biggest one. That’s rule number one.

Number two. Light is the fastest thing in the world. At a speed of km/h, it can get to the sun in just eight minutes, which is about 150 million kilometres away! The closer you get to the speed of light, the slower time goes. If you are travelling at the speed of light, time ‘freezes’! That’s a I am gonna say for today. Check back next time for more posts on time!
