The things you can do with maths

Is this proof that 2 = 1?

If x = 1 and y = 1 then x = y

STEP 1

Multiply each side by x

x² = xy

STEP 2

Subtract y2 from each side

x² - y² = xy - y²

STEP 3

Factor each side

(x + y)(x - y) = y(x - y)

STEP 4

Divide out the common term (x - y)

x + y = y

STEP 5

Substitute the values of x and y

1 + 1 = 1

so,

2 = 1

Curiosity takes one more step for Neil

What a terrific moment today when Curiosity Mars Explorer landed successfully. The people at NASA involved in this project must be very relieved and extremely proud. Lets hope the results from this achievement spur humanity on to greater efforts to explore the solar system. Maybe the example of CERN and the LHC will serve to show what can be achieved working together and that the international community will finally get together. I’d love to see humans stand on the surface of Mars.

While writing about great endeavour and achievement it is great to see all these Olympic athletes (winners and other competitors) giving their best efforts. As someone who has worked at my various sports for all my life I understand the effort and sacrifice. Having watched rowers finish a race, to see how much of themselves they have given and the disappointment and feeling that they had somehow let people down, this upset me when I then thought about the ignorant,arrogant waste of space students I often encounter at work.

Finally I was saddened to see that Neil Armstrong had died recently. He was one of my hero's and an inspiration. One of my first memory's was getting up early in the morning to watch that first moon landing on the TV. Just think that in the whole history of humanity only eleven people have stood on another planet and looked back at our small and insignificant dot that we call home. Neil Armstrong was the first human to ever stand on another planet (well moon actually), what courage must that have taken. Yet when he returned to Earth he remained the quiet, humble man he always was. Maybe we could do with more like him, maybe we could do with people asking why we have not moved further after all it was forty years ago when the last man Eugene Cernan stood on our moon (it's all politics and it's all garbage - mankind needs more than our small planet to survive and to do that we need to be together and the thing holding us down are politics, greed and relgion.)

Here are some quotes from Neil:

It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.

The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet and our visions go rather further than that and our opportunities are unlimited.

I fully expected that, by the end of the century, we would have achieved substantially more than we actually did.

I think we're going to the moon because it's in the nature of the human being to face challenges. It's by the nature of his deep inner soul... we're required to do these things just as salmon swim upstream.

All of these quotes say something important: humanity can be great, certainly so much more than we are, when we allow ourselves to be. That we live on a small part of the Universe, nothing special and that we need to reach for more. That we have not allowed ourselves to move on from those days of Apollo.

A quick post

The ozone hole over the arctic was the largest ever recorded. The hole was actually twice as large as the previous largest and lasted for a substantially longer period than normal.

Interesting article about the often held belief that climate change is in fact a myth, something made up by the science community. Part of the problem is related to lack of understanding and our apparently less informed cousins in the U.S. It appears that anti-climate change groups (deniers not sceptics) are slowly getting a foothold in the US classrooms where children are beginning to be taught that climate change is either not related to mankind, or not occurring at all. Many of the intrusions of legislation into the classroom suggest that a more balanced view about climate change is to be taught. Now I understand that a balanced view is good, but when the overwhelming evidence is for climate change, it is hard to see how anybody can justify teaching anything contrary. If this ability that the majority of humankind has for self delusion continues, we may find that it’s too late to control.

That Reminds me

With the release of the Edgar Rice Burroughs inspired movie of John Carter (based on the John Carter on Mars series of books) I have been reminded of how much I really enjoyed these books as a kid. Well having been re-informed about them I intend to make time to reacquaint myself with them - well Just as soon as I have finished reading Stewart Lees book about his time as a stand-up comic. If you haven't watched Stewart Lee let me suggest you search him out.

Here's a link to John Carter trailer and another for Stewart Lee

Power the world

I have recently been reading about microbial fuel cells (MFC's), a really interesting concept that can use microbial activity to degrade many types of substrate such as waste water, sewage sludge etc ad in the process produce electricity.

Although this technology is in its early stages, many of the reports seemed fairly confident that within the next ten years these MFC's can be used to replace some battery applications, or provide small scale plant works with electricity.

I wonder if these systems could be adapted to work from food waste?

More Gallery

I have put a few more paintings in the gallery, probably the last for a while. There will be more when I have finished those that I've recently started. I'm learning to paint with a different type of paint and this requires different techniques so it will be interesting to see what I get.

Recent learning

I have just finished watching

Ri Discourse: Jon Butterworth - 

Electroweak Symmetry Breaking

and LHC on the Royal Institution Youtube site. Although I do have

 an understanding of the theories this video advanced my knowledge.

And just as a counterpoint to this high brow stuff have a look at this.

More soon

Climate change; what do you think?

Just read a recent article titled

Climate consensus 

cracking open - 

or not

It made interesting reading, especially if you believe, as I do, that science will be our saviour through logical reasonable investigation and argument. It was also a little worrying and seriously so if you read some of the comments from people clearly ignorant of any facts and who see everything as a big conspiracy.

Royal Institution

Nothing much to say of late. I have written about quite a few things but not published them, don't know why. Perhaps it's because I have many other things going on at the moment (too many other worries).

I am in the process of becoming a member of the Royal Institution, which should be good - promotes science and the use of thinking.
