Grass

As one of my summer holidays projects, I have done grass.  Most people think of it as a weed, but after watching ‘How to Grow a Planet’, I changed my mind. Read the pdf document and learn about the amazing evolutionary history of grass: how it battled against giant trees (and won, with fire), staved off herbivores (for a while) and helped spark human civilization (by starting farming).  Once you have read it, you should still watch ‘How to Grow a Planet’, it is very interesting.

Death of the Dinos

I have made a new project, it is called ‘Death of the Dinos’ and it is about the theories of how dinosaurs may have become extinct. It also has ways to stop those theories if they happen to us. If you have Microsoft PowerPoint 2013, you can see some awesome transitions I have done; if you have an older version, you won’t see the transitions but you can still read the text.

The Standard Model Extension

In the last post I explained The Standard Model, there is just one problem, it is incomplete. I have created my own theory of how dark matter and dark energy could fit in The Standard Model. In my theory, there are two anti-quarks for dark matter called the Jeevan quark (sign of G) and the Jai quark (sign of J). As the dark matter quarks are anti-quarks the charges would be -2/3 for the G quark and +1/3 for the J quark. Dark energy is a lepton in my theory and is called zeta (sign of ζ) named after the 6th Greek letter. I believe the reason we haven’t seen dark matter and dark energy is because a boson called delta (sign of δ) named after the 4th Greek letter, detects particles that aren’t dark and alerts the dark matter and dark energy to shrink. Some people think there is a graviton for gravity, but I think gravity is part of mass and mass is explained in the Higgs boson. Here is the complete diagram:GJ-Zeta Standard Model

I bet you didn’t notice the name of this post has 2 meanings. 😉 😎

The Standard Model

Recently, my dad taught me ‘The Standard Model’ of physics. It is made up of quarks, leptons and bosons. Three quarks make up a proton or a neutron. It depends what the combination of quarks are there to make different hadrons (proton/neutron), e.g. 2 up quarks and 1 down quark make a proton, 1 up quark and 2 down quarks make a neutron. I know that because an up quark has a +2/3 charge and a down quark has a -1/3 charge. The Higgs Boson is an undiscovered particle that will explain mass. I drew a diagram to explain better:

I also drew another diagram showing what makes matter, it explains how crucial quarks are to make everything. It also shows what everything is made of and the layout of atoms, molecules, nuclei and quarks. Oh and what quarks are made of is still a mystery (some people think it could be strings, but that sounds silly to me, haha silly strings 😉 😎 ).  Here is the diagram:

Video Game Addiction

This writing is about video game addiction as you can see in the title. Video games have changed the lives of many people including people who make games and game addicts. In 2007, Harris Interactive’s online poll gathered details on youth opinions about video game play:

  • Sample of 1,187 US youths aged 8-18
  • 81% played at least once a month
  • Average for teen girls: 8 hours a week
  • Average for teen boys: 14 hours
  • 8-12 year old girls: 10 hours
  • 8-12 year old boys: 13 hours
  • 8.5% can be classified as pathological or clinically addicted
  • Players of MMORPGs are most likely to be addicted and spend the most amount of time

Tech Dirt has an interesting article about video games.  Tech Dirt in this article is unbiased and very neutral unlike many other sources. You can tell it is neutral because it actually said how studies can be biased and the conclusion says how video games can be good and bad in different ways. Tech Dirt also summarises psychological studies about how games can help gamers feel a sense of achievement.

I think playing video games is good and bad. I think playing video games is good because they can teach you things and encourage you to do new things. For example, Little Big Planet can make people want to be architects, designers or builders. Playing video games can be bad as well because shooting games might make people become murderers.

My dad made a graph of his game playing throughout the years so I made one too. Here they are:

Average hours of video game playing per week over the years for Dad

Average hours of video game playing per week over the years for Dad

Average hours of video game playing per week over the years for me

Average hours of video game playing per week over the years for me

As you can see neither my Dad nor me could be considered as video game addicts at any time (despite what my sister always says – her average is only about an hour or two a week).  My Dad has played many different computers and consoles and at the peak he averaged 14 hours a week, for me this total is 10 hours.  Currently I play a lot of PES 2012 on the PS3 (I will review some more games in the near future).

Bose-Einstein Condensate, The Sequel

One day when I was thinking, I had a great thought:  What happens when you put Bose-Einstein condensate into room temperature or into a very hot place very quickly? So usually it is made by freezing liquid helium to ultimately low temperatures (like a fraction above absolute zero (0 Kelvin or -273 degrees Celsius)). Normally if you freeze something and then heat it, it goes back to its original form, e.g. steam –> water –> ice –> water –> steam. But Bose-Einstein condensate would probably change permanently when the helium atoms turn into waves.

Mum said that it is the same as with eggs, once you boil an egg then even when it gets to room temperature it stays a solid. But eggs are not from a single similar molecule (water is just H2O and Bose Einstein condensate would have been helium). Eggs are surprisingly complex. And so is Bose-Einstein condensate but in a different way. I couldn’t find anything on the internet about this idea; surely somebody has done this experiment already.

The Symphony of Bang Goes The Theory

When I first heard this I was thinking how do they do that? Then my dad told me they used a program called autotune. So I looked on Wikipedia and it said it is used to correct the pitch in voices and instruments. I found it amazing that it could change normal speech into a song.

You should check out the BBC website.  Also, definitely take The Big Risk Test that was made by Cambridge University.  I got a score of 85 and 80 and in the spinner round I got 215 (my Dad got 115, haha).  Tell me your scores in the comments.
