Can you find everything on the Internet?

Hi,
so over the last Sunday I have spent a LOT of time doing physics. This meant mainly analyzing the problem (which was the movement of rocket through the Solar System) and then ton of writing and rewriting but in particular researching on the internet. I had real trouble sometimes and spent countless minutes search information like “energy density of RP-1” which is a rocket propellant and how much energy you can get from it when you burn it.

This got me thinking about how the internet is spot where one can find basically anything but you should never forget that this makes it a huge dumpster.

Let me give you a very simple example that I can remember right now. Just type into Google “Sun”, I did this because I wanted to know the radius of Sun [1]. The first link will probably be www.thesun.co.uk that is British magazine as you might already know (and a bit controversial as you might find out when you click on the link). Of course, I did not want to know how some celebrity’s kid spilled soup so I clicked the second one (which was Wiki). What I simply wanted to illustrate is that internet will give you what you ask for, except that you do not know what you are really asking for. The most visited webpages are made for quick eyes, simply who sets the best clickbait gets to the top so it is going to be difficult to get some hardcore explanation of a given problem. This is partially the reason why I wanted (and luckily got) a textbook for astronomy. I realized that it is no longer an option for me to learn from the internet (as I knew it back then) and decided that I need solid source of information [2]. So yes, internet will quickly give you the video about biggest black holes but you won’t know why they are so big. After you type in the exact question you might at best get binary answer (this one is a trick, if I remember correctly we do not know how come supermassive black holes be so big). In short, internet does not go deep, just check out channels like SciShow for example. You need to spent way more time digging in this dump if you gonna find anything. It also helps to understand what you are looking for, because internet is not best in explaining.

[1]You would not believe how tricky it is to find if this is the same information as the radius of the surface of the Sun (and it is).

[2] It is possible of course, you just have to do way more work.

Serious problem of multitasking

Hi,
when I was yesterday writing about procrastination, most of the memes I found were negatively turned towards procrastination while multitasking seems to look like a good thing to do, by most of the people on the internet.


Oh yes, I am trying to say that multitasking is really bad, but first lets define what exactly means to multitask.

So multitasking is apparent doing of several things at the same time.
I say apparent because what people actually do, is that they change their tasks very often so it seems that they are doing more things at the same time (this is exactly what computers do, switching between various tasks).

This can mean many things like: cooking and calling, emailing and eating, chatting and learning and so on, what is worse you add more and more things to do at the same time.

This takes price. Every time you switch from one task to another you must remind yourself what this task is and that takes energy so your brain eats glucose like crazy. What is even worse is that this switching between tasks releases dopamine.

Dopamine is hormone which does lot of stuff and is connected with Parkinson’s disease. This hormone is kind of good for you and your brain remembers exactly from what activity dope of dopamine was released. This is why you want to perform the task again, and again. Dopamine is stimulating your brain and this is where most of the addictions come from. So yes, what I am trying to say really is that you can get addicted to multitasking.

So what other problems are there with multitasking? Well it is energetically inefficient but also it does not let you to dive to one problem and solve it properly with your best. Sometimes multitasking can even double the time it takes to finish the task, while you still think that you are extremely efficient when multitasking.

Last thing is that when you are actually learning and playing games at the same time, the knowledge from learning, even if you learned something, may be stored in the part of brain tagged as “fun or recreation or games”. What then happens is that you are not able to properly remember those things when you are learning something similar and your brain should normally say: “Oh yeah! I know this part already!”

So my best advice, stop it now! As I said in the post about procrastination, try to learn not to be distracted by other things around and focus only on one task, the most important one.

Capturing territory, Facebook page

Hi,
I am here to announce that I just made a facebook page for my blog it is called Science and rationality as my wordpress.
WHY?
Because I want to extend my virtual territory and maybe collect some people from the internet.

Mostly I plan to use my facebook page for short news and links to wordpress.
I will see how it goes and if any people are “liking”.
