Questions & Answers

Q: How are the London Olympic mascots different from previous ones?

The London Olympic mascots are unique as they are made of stainless steel, a departure from the traditional fluffy animal mascots seen in previous games. This change adds a scientific touch to the Olympic symbol.

Q: Why was iron problematic in the early days for making tools and swords?

Iron was problematic for making tools and swords in the early days because it was a soft material that broke easily. This weakness posed a vulnerability during battles, leading to advancements in iron treatment methods.

Q: What was the breakthrough in making steel, and who discovered it?

The breakthrough in making steel came in the early 19th century when English industrialist Bessemer discovered that blowing oxygen through liquid iron removes carbon, resulting in pure iron. This process allowed the addition of just the right amount of carbon to create good steel.

Q: How does stainless steel differ from other types of steel?

Stainless steel differs from other types of steel by containing additional metals like nickel and chromium. These metals prevent rusting, making stainless steel ideal for items like cutlery and bridges, providing durability and a shiny appearance.
