What is this thing 6 of them are different from each other. 3 of them were designed by the same sculptor?

A drawing is placed on one of them.


Whose work is best characterized by the use of solid volumes resting firmly on the flat and horizontal surface of this earth?

The work of sculptor Donald Judd is best characterized by the use of solid volumes resting firmly on flat, horizontal surfaces. His minimalist approach emphasizes geometric forms and the relationship between objects and their surroundings, often using industrial materials. Judd's pieces are designed to engage with the space they occupy, creating a dialogue between the artwork and the viewer's perception of form and space.


How many ways to make an ice sculpture?

There are numerous ways to make an ice sculpture, depending on the desired design, tools, and techniques used. Common methods include hand carving blocks of ice using chisels and saws, employing power tools for more intricate designs, or using molds to create specific shapes. Additionally, artists can combine different techniques, such as layering ice or adding color, to enhance their sculptures. Ultimately, the creativity and skill of the sculptor play a significant role in the variety of final outcomes.


How do they make coins?

Hammer Forge Method:First they cut out round blanks. Then they design a template of the reverse of the image and mount it on a drop hammer forge that pounds the image into the blank. The hammer forge method is suitable mostly when making small numbers of coins.Machine Method:Modern coins are made in such large quantities that production has to be mechanized.The front (obverse) and back (reverse) designs are first created by an artist. A sculptor then cuts these designs into circular pieces of sculptable material, usually plaster. The plaster models are much larger than the actual coins so that the sculptor can work on them more easily and with greater detail.Next the designs are traced by a special machine called a reducing lathe. The lathe mechanically "reads" the designs off the model and makes smaller copies in metal, the same size as the coin itself. The metal copies are hardened and used to force a reverse image into dies - still other pieces of metal that will be used to strike the coins themselves. Many dies can be made from one master copy, allowing for mass production. The dies are then mounted in mechanical coin pressesThe metal that will be used for the coins comes in huge rolls that have already been flattened to the correct thickness. They're unrolled and fed into a machine that punches out blanks (planchets) that are approximately the same diameter as the finished coins.After being punched, planchets are fed into an "upsetting" machine that squeezes them very slightly in order to add a raised edge. From there the planchets are fed into presses that have the obverse and reverse dies mounted opposite each other. Each planchet falls into a holder called a collar. The dies are then forced together which strikes the images on each side. This process happens at very high speed and on an enormous scale to fill the demand for millions or even billions of coins each year.


Which two well known mathematicians were born on April 15?

Leonhard Euler (German pronunciation:15 April 1707 -- 18 September 1783) was a pioneering Swiss mathematician and physicist. He made important discoveries in fields as diverse as infinitesimal calculus and graph theory. He also introduced much of the modern mathematical terminology and notation, particularly for mathematical analysis, such as the notion of a mathematical function.[2] He is also renowned for his work in mechanics, fluid dynamics, optics, and astronomy.---wikipedia.comLeonardo di ser Piero daVinci ( pronunciation (help·info)) (April 15, 1452 -- May 2, 1519) was an Italian polymath: painter, sculptor, architect, musician, scientist, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist and writer. Leonardo has often been described as the archetype of the Renaissance man, a man whose unquenchable curiosity was equaled only by his powers of invention.[1] He is widely considered to be one of the greatestpainters of all time and perhaps the most diversely talented person ever to have lived.---wikipedia.com
