THINGS EVERY PERSON SHOULD KNOW ABOUT SCIENCE
Added on: 16th Oct 2016
SCIENCE IS PART OF WHAT MAKES US HUMAN
In its most basic form, science is applied curiosity.
You look at the world and think to yourself
“why is it that way?” You then come up with
an idea, you test it and see if your idea passed the test.
If not, you come up with another idea.
This is the scientific method.
THERE IS NO "OFFICIAL HIGHEST AUTHORITY"
There is no group of people sitting around dictating the
laws and theories of science. This may sound
elementary to some, but to others, this is critical to
understand. Anybody can go out and try to disprove
scientific theories. In fact, that is what scientists do
every single day. They try their best to disprove
their theories to see if there exists a better one.
As you may have been able to deduce, science is
collaborative. This means that it is the sum of
human knowledge up to a certain point.
All life on Earth encodes the main information about itself
and passes that information down through DNA
Although there is a lot of fear associated with this word,
radiation is ubiquitous and life depends on it. And just
to ease your fears about getting cancer from your
mobile device, let us remind you that your own body
emits more radiation than your mobile phones do.
The type of nuclear reaction occurring in a power station
is very different from the type of nuclear reaction that
occurs in a bomb. So just like with mobile phones, that
fear of a nuclear explosion happening next to your
house isn’t very realistic.
Everything is chemicals, which consist of elements, which
consist of atoms. And 99.99% of atoms are just empty
space. In fact, the only reason your hand doesn’t go right
through the table is because of these “empty” atoms
repelling each other by way of various forces. And the
reason you can’t see through the table is because those
atoms reflect photons.
ANALOGUE VS DIGITAL
Digital information is binary. It’s 1’s and 0’s. The real world is
analogue. It’s all light waves, sound waves, etc.
Converting analogue information to digital involves
some loss of information but it is worth it because
digital data is easier to store.
