Here is a poster of Kuiper and Oort Objects
This poster/wall chart was produced by SPACE.COM as a quick guide to Kuiper and Oort Objects.
Knowledge of the Kuiper Belt and the Oort Cloud is sparse but it is known that some objects have very eccentric orbits. I think we can expect many more objects to be discovered in this area in coming years.

There is a new class of objects in the Solar System – Dwarf Planets – which now includes Pluto.

This Chart Describes Cosmic Inflation and Expansion of The Universe
I’m sure we’re a long way from hearing the last on Cosmic Inflation and Expansion of The Universe, but here is a SPACE.COM chart briefly explaining it.
On 30th January 2015 Space.com announced: Inflation is not proven to have occurred as previously suspected in March 2014. The evidence for it has been discredited. Check it out at Space.com where Evidence for Cosmic Inflation Theory Bites the (Space) Dust.

What Is Earwax?
I’ve often wondered what is earwax all about but never specifically investigated it. Well today I just happened across this article on the BBC News website in the Health section and now I am the wiser.
It’s entitled: ‘Secretion secrets: things you didn’t know about earwax’. It discusses the following five issues:
- How it gets out of an ear.
- It’s anti-microbial properties.
- It matters where your family is from.
- A vacuum rather than a syringe might help clear it out.
- It can be a pollution monitor.
I expect people with earwax problems may find section 4 of interest since it says ears can be cleaned with a specialised vacuum cleaner. See example below:
It goes on to describe how this is a more pleasant and more efficient procedure than syringing. If you haven’t seen it here is the featured image of the cross section through a human ear.
WARNING: Do not try using a domestic vacuum cleaner for cleaning ears.
Observing The Reaction Of Dry Ice In Water
I always wanted to try this (put dry ice in water) and last year I got the opportunity. When I bought some meat from Donald Russell it was delivered packed in dry ice (frozen CO2) i.e. solid carbon dioxide. This dry ice was used to keep the meat cool in transit. The meat and dry ice are transported in a polystyrene box which provides lots of insulation. However the heat does percolate a package like this and the dry ice sublimates, but usually there is some left on arrival. If not the meat temperature may rise too high. So I had a source of dry ice.
The first thing I wanted to do as soon as the meat was stored in a cool place was put the dry ice in water and watch it bubble away and the vapour flow out and down the side of the container. I caught it on video below:
The title ‘Heating May Make Us Fat’ has no spelling mistake.
Check out this article at the BBC where Dutch researchers at the Maastricht University Medical Centre recommend heating homes to no more than 19°C (66°F) because:
Heating May Make Us Fat.
Below that temperature (19°C) they say our bodies continue to burn calories to keep us warm.
Interestingly the same article suggests, further on, that heating above 23°C (73°F) also causes us to burn calories by sweating to keep cool.
This post contains instructions on how to avoid spilling juice from cartons or Tetra Paks®, with a rectangular cross-section, while opening or lifting them. It’s quite natural to grip cartons by the easiest method (the broad sides) while opening them, or lifting them when they’re still full, causing the contents to pour or squirt out inadvertently. Cartons with a square cross section are indifferent to the sides that are gripped when lifting or pouring.
You go to the refrigerator and take out a new cool carton of juice. You hold it firmly and take off the seal and juice spurts out at you and runs down the side of the carton, or you pick it up after removing the seal and juice pours out as you grip it. Before you’ve got it in a glass you’re in a mess. This is usually caused by the way you grip the carton. Continue reading “Spilling Juice From Cartons or ‘Tetra Paks®’”
