How to make a cloud chamber

How to make a cloud chamber for observing cosmic rays using (mostly!) everyday household items. Presented by Suzie Sheehy (http://suziesheehy.co.uk/) and videography by Andrew Steele (http://andrewsteele.co.uk/).

This video came about as a result of setting up a workshop building cloud chambers for the APPEAL (Accelerator and Particle Physics at A-Level) teacher conference, in the John Adams Institute for Accelerator Science at the University of Oxford. The workshop was adapted from the CERN Cloud Chamber workshop, with the assistance of MIck Storr.

Please note that all activities involving dry ice and/or alcohol should be accompanied by a proper risk assessment and safety equipment. We cannot take responsibility for the outcome of any activity undertaken as a result of this video.

3D Printing in Ceramics

New AHRC film looks at how creative innovation can translate to new products.
Arts and humanities research generates innovative ideas with real-world applications and commercial potential. One example of research that is realising this potential and contributing to economic growth is an AHRC-funded Knowledge Exchange project at the University of the West of England.
In this film we see how researchers at the Centre for Fine Print Research, Led by Professor Stephen Hoskins and his team, have developed new methods of creating ceramics using 3D printing technology and worked with Denby Potteries to test designs and develop prototype models in ceramics.
Through this method, ceramics are built up layer by layer using a specially-created -- and now patented - ceramic powder. They are then fired and glazed in the usual way. 'Printing' ceramics in this way means that highly intricate and complex ceramics can be created that would have been impossible to achieve traditional methods. This has opened up commercial potential through quicker manufacturing processes and new design options. Gary Hawley, Senior Designer at Denby, praised the partnership between his company and researchers, saying that the new process is "pushing the boundaries of what is possible".
The film concludes with Professor Hoskins' inspirational view of what the future for 3D print technology might look like. This includes the announcement of an exciting new AHRC-funded project which will see the Professor Hoskins and his team to undertaking a major investigation into a self-glazing 3D printed ceramic, inspired by ancient Egyptian Faience ceramic techniques.The process they aim to develop would enable ceramic artists, designers and craftspeople to print 3D objects in a ceramic material which can be glazed and vitrified in one firing.

The team hopes to bring ancient tradition into the 21st century, joining together old and new hand-in-hand in a project that continues to push boundaries in this area of ceramic research

Housing Disaster in China

This project is about housing disaster in China.

Is property prices in China so high? And how high is it? What problems are caused the high property prices? What new problems show up as China's property prices falling? If we don't take any effective measures and policies to solve this problem, the real Housing Disaster will coming soon. So, what should we do to change this situation?

Problem:

1. When the chinese property prices are higher and higher, most of the people can't afford to buy a house. That's the reason why so many new residential buildings idle and wait
for selling out.

2. At the same time, estate developers continue to purchase agricultural land and build new residential building, resulting many landless and jobless peasants.

3. When the property prices being lower, those mortgage slaves don't want to see house prices falling, because they had already paid a lot before getting their house. Not only the
low-income but also the majority of the residents in China can't afford to buy a house. They are waiting and watching the situation. Though a lot of residential buildings are
still idle and wait to sale.

4. Economists have estimated that about 45% of China's GDP are relied on the real estate industry, also the real estate market directly impacts to other sectors like construction, steel production, cement production, electricity and household appliances and so on. If the real estate bubble burst, these people who work on it would facing the unemployment.

So if China's economy of real estate is a serious slump, at that time, many people will still unable to afford to buy a house.

Solution & Answer:

1. If still so many residential buildings are idle and wait to sale. Maybe we could rent these residential buildings which are stayed more than 6 months out. At the same time, it's cutting down the stress of the real estate market. That we should rent it to alleviate the pressure of real estate developers and property market. Keep the high price and substantial price cuts are not a wise move.

2. We should't be blind to the construction of more residential buildings. Because of the crazy expansion of real estate developers that made many landless and jobless peasants in China. So, the real estate developers shouldn't continue to purchase the agricultural land and build more new residential buildings any more.
