The Comical Side of Scientific Experiments!

Hi There,
Some readers of my blog have said that for a blog on `happy living’ my posts are too serious and heavy! So today I intend to ‘lighten up’ and talk to you about a couple of ‘Scientific Research’ Experiments that seem comical to me!
1. Is ‘swinging your arms when you walk’ an efficient action? Or is it just a throwback to our evolutionary ancestry – when we used to go about on all fours? Doesn’t swinging the arms involve muscle movement and mean more energy usage?
I think I could have answered that question without any scientific study (just by using simple instinct and common sense), as ‘Yes it is more efficient because it is natural!
However Biomedical Researchers have conducted a scientific study on the above ‘all important’ question at the University of Michigan at Ann Arbor.
Method:
A mechanical model was constructed to study the dynamics of arm-swinging. Then 10 volunteers were asked to walk with a normal swing, a reverse swing, arms folded, and held stationary at their sides. The energy usage for each style of walking was calculated from the amount of O2 consumption and CO2 production while the volunteers breathed in and out.
Study Results:
- Arm swinging while walking has low energy costs because it requires little rotational twist from the shoulder muscles compared with holding the arms still, which used up 12% more energy!
- The pendulum like swinging of the arms helped to dampen the bobbing up and down motion of walking which caused a loss of energy in the lower leg muscles! If the arms were held still, this bobbing movement (called vertical ground reaction) caused an increase in energy expenditure of 63%!
- Using a ‘reverse swing’ or an opposite to normal swing (that is right arm in sync with the right leg) caused the energy expenditure to go up 25%.
Conclusion:
Arm swinging when walking is more efficient than holding the arms still or arm swinging in reverse!
The second experiment I am going to describe should take the Guinness Record for being the most ‘frivolous and funny’ experiment ever undertaken in the name of science! I read about it years ago so I can’t remember the University involved, but its very frivolity makes the experiment hard to forget!
2. Does the size of the female breasts increase in the mornings as opposed to at night?
I would be tempted to ask “Who cares?” Anyway some scientific researchers thought it was important enough to conduct a rigorous study!
Method:
They devised an ingenious plan to measure the volume of the breasts. A basin filled to the brim with water was placed in a larger glass container at about waist height. The female volunteer had to bend forward carefully and immerse her breasts in the basin of water. The amount of water displaced overflows into the larger container. This water was then measured to give the volume of the breasts.
So the volunteers had to do this at night before going to sleep and in the morning immediately on waking up, while the researchers measured the volume of displaced water each time. After several days the average volume in the morning as opposed to that at night could be accurately figured out!
Results:
I have no idea because the question was never important enough for me to remember the answer!
Conclusion:
I know that some sectors of the population (such as Playboy magazine and Voyeurs Anonymous etc.) may totally disagree with my conclusion! However, to me it constitutes a colossal waste of funds and time and intelligence to conduct inane experiments like these!
Seriously though, sometimes I feel that I too am guilty of treading the same ‘scientific research’ path in this blog on Daily Happy Living! Because most of the ideas I share in this blog is ‘common sense’ and does not need rigorous study.
Unfortunately however, common sense has become so uncommon nowadays because we have given up our right to think for ourselves! Thus this blog may still serve a purpose and not be considered as frivolous as the above scientific experiments.
So I give myself permission to continue boring (or inspiring) you my readers for some time to come! Do keep a lookout for my next post.
Expect Happiness!
