Our Universe is a remarkable place and not a little odd in some of the ways it works. For instance have you ever heard of left and right handed molecules ? Or been told that, chemically speaking, an orange is a ‘left-handed’ lemon!
There are several ways we could measure what we are made of. We could classify ourselves as amounts of fat, bones, and muscle. Or maybe we could express ourselves by percentage of water (about 50-60% if you really want to know).
Why Does Water Freeze?
In a Nutshell … Water freezes because water molecules stick to one another when they get cold and slow down.
There is little doubt about the deliciousness of chocolate. But its health benefits are less clear. Chocolate has been implicated in causing a litany of problems, including acne and obesity. In large enough quantities it even has the potential to poison people. HOWEVER in recent years studies have found that eating small amounts of the right kind of chocolate can actually be healthy. Why? The short answer lies in the chemistry of...
We at guernseydonkey.com are always keen to promulgate that ever exapanding ‘body of knowledge’ we like to call “intenet fluff”. Accordingly we recycle here for your delectation a story that seems to have begun its life way back in 1997 when the internet was still young. Multiple examples now exist and its opening often varies – who the setter supposedly was and at what institution – but the core of the piece is always the same. Enjoy! 🙂
This is one of those urban myths that refuses to die. The idea that glass is really a viscous liquid, so thick that it takes centuries for it to flow. But what is the truth ?
Reality is sometimes stranger than we’d ever credit. Believe it or not but Scientists are actually saying that they can prove that Adam & Eve, that is a single set of ancestors, are parents to us all!
Are you a Bibliophile, someone who loves books? If you are you’ll know the joy of buying, collecting, owning, (smelling?), touching and of course reading these textual marvels. As a bibliophime, is one of your favourite pecadillos the scent of a new book or the musky thrill of an old books smell? In this article we look at the chemistry behind that guilty little pleasure otherwise known as Bibliosmia.
A valentine’s day conundrum for you : Why does an X stand for a kiss? and why do humans kiss anyway?
Does tea have more caffeine than coffee? This is one of those perenial questions.
Water is one of the strangest chemicals in the universe, and many of its strangest features turn out to be essential for life as we know it, particularly the almost unique property of water related to freezing. So why does it float when it becomes a solid?
What is Love ? : A very deep and involved question. However in this article we will restrict ourself to the scientific point of view. What is going on in our bodies, and brains when we fall in love or see the object of our inner most desires.
Scientists in Zurich, Switzerland have up with a sensitive new way to analyse the composition of almost any surface, including human skin by blowing a stream of nitrogen across the surface under analysis and collect the gas together with any debris that it dislodges. The material is then fed into a mass spectrometer that can pick apart the chemical composition of anything present on the surface.
A bar of soap is a chemical miracle – a little scented block that unleashes molecular forces when dunked in water. In this article we look how this little miracle actually works.
Fire – one of the most primitive and yet intriguing of the ‘fundamental elements in our world. Indeed one of the things that differentiates mankind from the rest of the animal kingdom is his ability to make and control fire. but : What is fire made of ? What is its atomic structure? What causes things to burst into flame in the first place and why can’t all materials be made to produce flame ?
