Vacuum decay and Trump

Hi,
today I want to do a fun post inspired by a meme that I saw some weeks ago on Theoretical Physics Memes. Well here it is:

https://qph.ec.quoracdn.net/main-qimg-0be932f563bde21614fc7bfbcff409d9


If you dont understand the joke, its alright, I will explain. If you do understand the joke you can continue reading for the sake of… reading?

Disclaimer: I have not been using disclaimers before but the truth is I am no physicist so I do not claim to actually comprehend this stuff.

So vacuum decay or also false vacuum is the idea that you could die any second. (See I am no physicist)

Basically fields (meaning electromagnetic and other types) want to get into the lowest energy state possible. Also electrons rather like lower energy states to be more stable so, if they have more than they “need”, they will radiate it away in form of photons. Now it is assumed that these fields are either in stable position (lowest energy level) or they might be in metastable position[1], which means that there is energy barrier between the metastable level and stable, if it is “reached over” and the field drops into lower stable or again metastable level it will release energy.

If we were in false vacuum[2] we would just need to reach over the hill to get to true one.

Since particles arise from these fields some new types would appear and Universe in this place would look a bit different inside. The reason why this is connected to the discovery of Higgs Boson is that the mass that it has indicates that we may live in false vacuum, if our physics is right than we could die any moment since the false vacuum is expanding almost at the speed of light.. means we can not know if it is coming on us or not, which also means that you do not need to worry really.

Now you understand the joke though if you are Trump supporter than you do not find it very funny in which case I pity you because it is great joke šŸ˜‰ [3]

[1]They can also be in unstable position but not for long.
[2]The name false vacuum has nothing to do with the vacuum of space.
[3]Proper explanation: it is so bad that Trump is elected, I hope that Universe will end soon, oh hmm.. what is the probability of it happening?

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.

DopamineĀ 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.
