Emmy Noether: Bucking the historical trends

...energy, which cannot be created or destroyed. It is Noether's theorem that relates this conservation law to the underlying symmetry of space itself – in fact, the conservation of energy is a result of the fact that empty space 'looks the same' from one moment to the next. Put another way, if empty space were rough or lumpy, then energy would be lost as things moved...

Retrofitting older buildings to help mitigate the climate emergency

...energy demand and associated carbon emissions is, therefore, a key strategy that has been highlighted by the UK Committee on Climate Change and is acknowledged in the Government’s recent heat and buildings strategy. However, 20-30% (that's over ten million homes) of the UK housing stock have heritage value. Many of these buildings aren’t officially designated, meaning...

...energy to do so, leaving less energy for growth and reproduction. Consequently, they up smaller in size. Aside from the impact this has on shellfish, several of the species affected, such as corals in the tropics or coralline algae in the waters around the UK, also play a key role in providing food and nursing grounds for fish. And less fish food leads to fewer fish for...

...energy he expends. These tools bring an apparent precision: Nash can quantify the calories in each cracker crunched and stair climbed. But when it comes to weight gain, he finds that not all calories are equal. How much weight he gains or loses seems to depend less on the total number of calories, and more on where the calories come from and how he consumes them. The...

...energy, but that is not always good: if we eat more calories than we use in a day, the leftovers will be stored in our bodies in the form of fat. However, their delicious sweet taste might tempt us to eat one more biscuit, just one more bite. Back in the day when people did not have much to eat, a food rich in sugars was a treasure: consuming it would give you enough...
