The top hardest substances known to man include diamonds, which are made of carbon and ranked highest on the Mohs scale, followed by materials like boron nitride, wurtzite boron nitride, and aggregated diamond nanorods. Other notable hard materials include corundum (sapphire and ruby), cubic boron nitride, and materials like moissanite and various forms of carbon such as graphene and carbon nanotubes. Additionally, certain synthetic materials like diamond-like carbon and various superhard ceramics contribute to the list of the hardest substances. These materials are often used in industrial applications requiring extreme durability and abrasion resistance.
Man at the Top - TV series - ended in 1972.
The Man of Steel, Iron Man 3, and Wolverine are the top ones so far.

The hardest stone is of course a diamond but if your just looking at the top three hardest stones then they would be as follows: diamond 10 sapphire 9 ruby 9 the top ten hardest substances though are: aggregated diamond nanorods 10.3 diamond 10 rhenium diboride 9 aluminum diboride 9 zirconium carbide 9 sapphire 9 ruby 9 alumina 9 carbium 9 boron carbide 9 silicon carbide 9 titanium carbide 9 beryllium carbide 9 borazon 9 stishovite 9 tantalum carbide 9 tungsten carbide 9 ultrahard fullerine 9 corundum 9 tantalum nitride 9 NOTE: this answer is in partial answered by other sources including: wiki answers article What are the top 10 hardest substances known to man? and on Google search engine
There is actually no scientifically accepted 'hardest' substance known to man and there are a lot of debates over this.It's a common misconception that diamond is the hardest but variations of substances like Boron and minerals like Lonsdaleite are actually tougher than diamonds.
One use is in top-of-the-line phonographs (record players); diamond, being the hardest mineral known to man, won't skip or wear down as the needle traverses the grooves of the album.
More information is needed to properly answer this question. The top 10 hardest firms in the world is too broad. Do you mean the hardest firms to get hired by, the hardest firms to work for, the hardest firms to sue?
Answer still needed, BUT:- Oddly enough, in today's Science News daily, Aug 5 2011, there is an article regarding the use of carbon nanotubes as a surface fire retardant on foam plastics used in furnishings. From NIST.

Diamond is the hardest naturally occurring material, scoring a 10 on the Mohs scale of mineral hardness. This means that it is extremely resistant to scratching and is used in various industrial applications due to its hardness.
Princeton, Harvard and Yale are generally agreed to be the top three universities.
Substances float on top of others based on their densities. When two or more substances are layered, the one with the lower density will float above the one with a higher density. This is governed by Archimedes' principle, which states that an object will float if it displaces a volume of fluid equal to its weight. Consequently, substances with different densities will stratify, with less dense substances on top.
