Can a knife cut an atom?

A knife cannot cut anything smaller than the blade of a knife. Since knives are made out of atoms, they can’t cut atoms. The splitting of atoms in atomic bombs happens as a result of a different process. However, even these atoms can’t be cut with a knife, because the atoms are smaller than the knife is.

How are modern swords made?

A forged blade is created by heating the metal and pounding it into shape. Forged swords may contain a single metal or a combination of metals. The easiest and most common form of forged sword uses a single steel alloy to create the blade.

Is obsidian a Monomolecular?

Cutting surfaces that are nearly monomolecular in width can be found in glass and obsidian, due to their unique physical structure. Glass and obsidian blades are even used for cutting microscopic sections for use in electron microscopes and other areas where objects must be very small.

Can obsidian split atoms?

Since obsidian will fracture down to a single atom, it is claimed to have a cutting edge five hundred times sharper than the sharpest steel blade, and under a high magnification microscope an obsidian blade still appears smooth, whereas a steel blade has a saw like edge.

Are thinner blades sharper?

Thicker blades will be stronger. Thinner blades will have a slimmer profile – which allows for easier and better slicing. The choice of blade thickness comes down to compromising between strength and slicing ability.

What is the strongest sword made from?

1060 carbon steel provides a good balance of strength and hardness. Many durable swords are made from this type of steel. It’s more popular than 1045 carbon steel but more difficult to make. 1095 carbon steel katanas can take and keep a much keener edge than katanas with lower carbon content.

What weapons did the iron Age use?

Many different types of weapons and iron tools were used during the Iron Age in Britain, and across the world:

• Daggers. Daggers were very common Iron Age weapons, and before this era, no iron daggers had existed.
• Shields. The Iron Age shield was usually oval or round.
• Spears.
• Swords.
• Javelins.
• Axes.

Do swords bleed?

“You can tell it’s blood,” he says matter-of-factly, “because ordinary rust turns the grinding water brown. If it’s blood rust it bleeds, it looks like blood in the water. Even 2,000 years old, it bleeds. If there’s blood on the sword and you start polishing it, the sword bleeds.

What is the structure of a carbon nanotube?

The structure of a carbon nanotube is formed by a layer of carbon atoms that are bonded together in a hexagonal (honeycomb) mesh. This one-atom thick layer of carbon is called graphene, and it is wrapped in the shape of a cylinder and bonded together to form a carbon nanotube.

What is the difference between single-wall and multi-wall carbon nanotubes?

Unique molecular structure – based on their structure we differentiate single-wall and multi-wall carbon nanotubes. Single-wall carbon nanotubes (SWCNTs) are one-dimensional carbon nanomaterials. They consist of sheets of graphene. These sheets are rolled up and form hollow tubes. Their walls are one atom thick.

What would it take to build a Ringworld?

Transmutation of elements, such as the predominant hydrogen and helium available within Jupiter and Saturn, would be necessary anyhow for enough (non-scrith) material to build the megastructure. As for the actual Ringworld building process, Niven sketched it as follows.

Why are graphene and nanotubes used in batteries?

Because the base of each nanotube is bonded, atom to atom, to the graphene sheet the nanotube-graphene structure is essentially one molecule with a huge surface area. Using carbon nanotubes in the cathode layer of a battery that can be produced on almost any surface.
