## What goes on top of a diamond problem?

The top number is the product of the left and right numbers, and the bottom number is the sum of the left and right numbers. The puzzle consists of the diamond with two numbers filled in; the task is to determine the other two numbers.

## What is the Diamond method?

Diamond Method for Factoring Polynomials

The diamond method provides another systematic way to factor second degree polynomials of the form ax2 + bx + c that are “hard,” that is, those second degree polynomials that have a value for a other than 1.

## What does a diamond mean in math?

The term diamond is another word for a rhombus. The term is also used to denote a square tilted at a. angle. The diamond shape is a special case of the superellipse with parameter , giving it implicit Cartesian equation.

## Are all squares diamonds?

A simpler explanation would be all angles inside a square are equal to 90°. If you have a shape that has 4 equal sides, but only opposite angles are equal, it’s a diamond.

## What is a diamond shape sign?

Diamondshaped road signs always warn of possible hazards ahead. These are traffic signs, temporary traffic control signs, and some pedestrian and bicycle signs. Pennant-shaped road signs warn drivers of no-passing zones. Round-shaped road signs are used for railroad signs.

## How many degrees is a diamond?

The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).

## Can lava melt diamonds?

The melting point of Diamond at about 100,000 atm is 4200 K, which is much higher than the temperature of lava. So, it is impossible for lava to melt a diamond. So, if the temperature of lava is above this, the diamond will burn (not melt).

## Does a diamond last forever?

Diamonds do not last forever. Diamonds degrade to graphite, because graphite is a lower-energy configuration under typical conditions. Diamond (the stuff in wedding rings) and graphite (the stuff in pencils) are both crystalline forms of pure carbon.

## Why is diamond so hard?

The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.

## What’s harder than diamond?

Scientists have calculated that wurtzite boron nitride and lonsdaleite (hexagonal diamond) both have greater indentation strengths than diamond. Source: English Wikipedia. (PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world.

## Can you break a diamond with a hammer?

As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. Whether something is hard or strong depends on its internal structure. This makes the diamond incredibly hard and is why it is able to scratch any other material.

## Is Obsidian stronger than diamond?

Diamond is harder than obsidian, as obsidian is a form of volcanic glass. Obsidian has a hardness of 5 to 5.5 on the mineral hardness scale, whereas diamonds have a hardness of 10.

## Will a fake diamond sink in water?

Water testing your diamond

If the diamond is real, it will drop to the bottom of the glass due to the high density of the stone. If it’s a fake, it will float on the surface of the water.

## What can damage a diamond?

Sudden extreme temperature changes can cause damage, however. Diamonds can chip or fracture from hard impact, especially in areas where the carbon atoms are not tightly bonded. These areas, called cleavage planes, are the major source of damage to diamonds (figure 2).

## Can Obsidian cut through diamond?

Cutting edge

Obsidian – a type of volcanic glass – can produce cutting edges many times finer than even the best steel scalpels. At 30 angstroms – a unit of measurement equal to one hundred millionth of a centimeter – an obsidian scalpel can rival diamond in the fineness of its edge.

## What is the sharpest item in the world?

The sharpest object ever made is a tungsten needle that tapers down to the thickness of a single atom. It was manufactured by placing a narrow tungsten wire in an atmosphere of nitrogen and exposing it to a strong electric field in a device called a field ion microscope.

## Is Obsidian weaker than diamond?

Surprising Things about Obsidian

Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts.

## What is the sharpest blade on earth?

Obsidian knife blades: overkill for slicing your sandwich. The thinnest blades are three nanometres wide at the edge – 10 times sharper than a razor blade. These are made by flaking a long, thin sliver from a core of obsidian (volcanic glass).

## What is the sharpest sword in history?

What was the sharpest sword ever made? Nanotech Used 2000 Years Ago to Make History’s Sharpest Swords. Damascus swords – sharp enough to slice a falling piece of silk in half, strong enough to split stones without dulling – owe their legendary qualities to carbon nanotubes, says chemist and Nobel laureate Robert Curl.

## Is there anything sharper than obsidian?

Obsidian is volcanic glass and CAN be made sharper than what is possible with steel, but many mistake this fact with a myth that obsidian knives will ALWAYS be sharper than steel. The obsidian blades you can buy in the under \$100.00 range will not likely be sharper than steel.

## What kind of knife does Gordon Ramsay use?

Gordon Ramsay’s Fox TV series Hell’s Kitchen, the contestants, uses Henckels knives, and on his online cooking course, Gordon uses Wüsthof. Both are two of the top knife manufacturers globally, and they’re known for quality products.
