Fission and fusion

Both fission and fusion are nuclear processes by which atoms are altered to create energy, but what is the difference between the two?

Care about your data!!!

Over 90% of the world's data was created in the last three years and by 2020 it is estimated that there will be 30 billion connected devices - all collecting data.

Our search history, contacts lists, website visits, are all being collected and often sold on.

Data can be sold and used for targeted advertising, but it can also be used to improve infrastructure and shared knowledge. It's also used to teach and improve artificial intelligence (AI).

But who owns this data? Many of us agree to giving our data away to companies when we agree to their terms of use. For some of us, this may seem like a small price to pay for a 'free' service.

But should we be giving this data away so easily?

Should we be able to trade our data for goods and services - or even treat it like a currency that we store in data banks?

If the future is being driven by data, then to own the future, we might well need to own our data.

Types of structures

All structures built can be classified into the following groups:

• Mass structures

Mass structures have been used since ancient history. They are based on the strength, resistance and permanence of natural structures that can stand the test of time. They are made up of large, thick stone blocks and the accumulation of materials used to provide support.

Some of the clearest examples of mass structures include the Egyptian pyramids, ancient temples, dams and stone bridges, some of which are still standing.

• Framed structures

These structures use resistant elements, such as vertical pillars and columns crossed by horizontal beams to form a framework. Today, they are used to construct the skeleton of buildings and to build scaffolding. A ladder is an example of a simple frame structure.

• Laminated structures

These structures are used to provide coverage and protection. They tend to be light and are usually fragile in comparison to other heavier structures. Harder, more resistant laminated structures are usually called exoskeletons.

The most common structures of this type include the outer panels of electrical appliances or the sheets of metal that cover a car.

• Hanging or suspended structures

This type of structure is based on the use of braces and steel cables to support solid structural elements. Braces and cables are often used in bridge-building projects, which tend to have one or two large towers, upon which the braces and steel cables that support the bridge rest.

• Triangulated structures

Triangles are the only geometrical shape that cannot be deformed. This means that an object made up of three rigid bars that form a triangle does not change shape when forces are applied to it. Therefore, triangulation, or making triangles with resistant elements, is the most effective way to make structures more rigid and more difficult to deform.

This type of solution can be seen in buildings and permanent structures, as well as temporary structures such as cranes, for example.

Ancient ruins

Ancient ruins give us a fascinating window into the past: how people lived, the spaces they inhabited and their daily lives. Historians, architects and travellers alike marvel at these remnants of time past, but it’s often hard to get a sense of what these spectacular buildings would have looked like at their peak. We´ll step back in time and recreate one ancient ruin in its original location

The Parthenon
Back in ancient times, this temple sheltered a monumental golden statue of Athena, the Greek goddess of wisdom, craft and war. Sitting atop the hill at the Acropolis, an ancient citadel in Athens, the Parthenon cuts an imposing shape. In 1687 it was severely damaged in the Great Turkish War, but much of the sturdy Doric architecture withheld the blast, and a good chunk of it is still intact to this day. Nowadays it’s a tourist hotspot attracting millions of visitors a year. Here it is, fully restored to its original glory. Athena herself would be proud.

Safety signs

The safety signs remind us of the risks related to our work and help to prevent accidents. These symbols have standardized terminology and fall into these categories:

• Warning: These signs are triangular and have a yellow background with a black pictogram. They indicate potentially dangerous situations that could permanently harm people.
• Prohibition: These signs are round with a red outer ring and a white inner circle. The pictogram is usually black. They indicate things that should never be done.
• Obligation: These signs are round and blue with a white pictogram. They indicate an obligation to comply with a certain action or rule.
• Information: These signs are square or rectangular, and are blue with a white pictogram.
• Emergency information: These signs are square or rectangular, with a green background and a white pictogram. They indicate emergency exits, first-aid stations, etc.
• Danger: Black and red with the word 'Danger' and an inner white space where the type of risk may be described.
