Studying Engineering

...energy and sustainability, electronics, or mathematical methods. Alternatively, you may wish to investigate our BSc (Hons) Natural Sciences degree, which allows you to choose a general science study route or to follow a more specialised route in biology, chemistry, physics, Earth sciences, environmental science, or planetary science. If you already have an undergraduate...

Ancient Rain: Historic monsoons could help us respond to climate change

...solar insolation received on Earth due to changes in the Earth’s position relative to the sun. Coupled with this external climate forcing, internal climate feedbacks (such as greenhouse gas concentrations) act to amplify the climate response to insolation. Assessing the behaviour of the monsoon during the penultimate deglaciation (~140-130 thousand years ago),...

What is a metal?

...energy depends on the shell it is in; in general as n increases, the energy of the electron also increases. The energy level occupied by electrons depend on the amount of energy in the system. At high temperatures (such as under a flame), electrons in the metal atoms will absorb heat energy and be promoted to higher energy levels. [Described image] ......

Preparation dyeing and finishing

...energy as the amount needed to heat up smaller amount of water is less. The dye makers have also produced dyes that have higher exhaustion rates (the amount of dye that transfers form the liquor to the fibre) meaning there is less waste and the wash off required (to remove loose dyes) is much lower. This again saves time, water and energy. Finishing the fabric is both...

What astronomical object was the Christmas Star?

...solar system and is a leftover from our planetary formation process. As the comet gets closer to the Sun and becomes heated, the ice can turn straight to gas carrying dust particles out into space. The gas and dust create impressive tails that can reach up to millions of kilometres in length. [Comet C/2020 F3 (Neowise) photographed during July 2020 in the northern...

Astronomy: images of the Universe

...Solar Orbiter. This information has enabled astronomers to understand the interplay of energy transport and magnetic fields in our nearest star. We also have a small number of resolved images of nearby giant stars. An example is pi super one Gruis (Figure 7b), which shows similar convective structure on its surface to that of the Sun. [Described image] Figure 7 Stars as...

Food, shelter and re-designing home as a living system

...energy, health and well-being. Multiplying targets existing infrastructure without simply adding more of the same. This may begin with policy design, for example, to introduce incentives for homeowners to retrofit oversized homes into flexible, multi-generation or non-traditional co-housing. Such incentives should increase for integrating food production, biodiversity,...
