# Did the invention of the tin foil phonograph have any impact on society?

Answer Yes, the tinfoil phonograph as invented by Thomas A. Edison in 1877 did have an impact! Previous to the phonograph's invention no one would have dared to believe a dead person's speech could come back to life! It was then thought that once a person died, all things verbal went with them, los…t forever. To be able to hear a dead person was almost surreal! Edison shattered all that! Even when the phonograph was written about in the newspapers, most people simply didn't and couldn't believe it was true. People just couldn't conceive the fact a simple metal device could do such a thing. Edison's invention proved so popular that "Scientific-American" sold plans so that a person could construct a phonograph at home.That helped cement the idea that anyone could actually accomplish what a inventor did in his lab. People made good money for several years demonstrating the machines in public venues. Everyone wanted to see one in action. Once shown and proven, the device changed people's ideas about permanence!

# Who invented the Tin foil phonograph?

In July 1877, while developing his telephone transmitter, Thomas Edison conceived the idea of recording and playing back telephone messages. After experimenting with a telephone "diaphragm having an embossing point & held against paraffin paper moving rapidly," he found that the sound "vibrations ar…e indented nicely" and concluded "there's no doubt that I shall be able to store up & reproduce automatically at any future time the human voice perfectly." Edison periodically returned to this idea, and by the end of November, he had developed a basic design. The first phonograph consisted of grooved cylinder mounted on a long shaft with a screw pitch of ten threads per inch and turned by a hand crank. Instead of paraffined paper, Edison used a piece of tin foil wrapped around the cylinder as a recording surface. The first phonograph had separate recording and playback mechanisms, but later designs combined them into a single unit. ( Full Answer )

# Who invented lattice method for math?

Lattice, or sieve, multiplication is algorithmically equivalent to long multiplication. It requires the preparation of a lattice (a grid drawn on paper) which guides the calculation and separates all the multiplications from the additions. It was introduced to Europe in 1202 in Fibonacci's Liber Aba…ci. Leonardo described the operation as mental, using his right and left hands to carry the intermediate calculations. MatrakÃƒÂ§Ã„Â± Nasuh presented 6 different variances of this method in this 16th century book, Umdet-ul Hisab. It was widely used in Enderun schools across the Ottoman Empire.

# When do you FOIL?

In math, you FOIL when multiplying two binomials. Really, FOIL is just the distributive property; it's just a rule to help make sure you multiply everything in the first binomial by everything in the second. So (x+1)(x+3) is an example of this. It is done by multiplying the first terms, outside term…s, inside terms, and then last terms. This is x 2 +3x+x+3. Simplified, this is x 2 +4x+3. ( Full Answer )

# How do you do FOIL?

There is also a special method, useful ONLY for a two-term polynomial times another two-term polynomial. The method is called "FOIL". The letters F-O-I-L come from the words "first", "outer", "inner", "last", and are a memory device for helping you remember how to multiply horizontally, without havi…ng to write out the distribution like I did, and without dropping any terms. Here is what FOIL stands for: .
That is, FOIL tells you to multiply the first terms in each of the parentheses, then multiply the two terms that are on the "outside" (furthest from each other), then the two terms that are on the "inside" (closest to each other), and then the last terms in each of the parentheses. In other words, using the previous example: .
Use FOIL to simplify ( x + 3)( x + 2) "first": ( x )( x ) = x 2 "outer": ( x )(2) = 2 x "inner": (3)( x ) = 3 x "last": (3)(2) = 6 So: Copyright Ã‚Â© Elizabeth Stapel 2006-2008 All Rights Reserved ( x + 3)( x + 2) = x 2 + 2 x + 3 x + 6 = x 2 + 5 x + 6 .
Many instructors in later math classes come to hate "FOIL" because it serves mostly to confuse students when they reach more advanced topics. FOIL tends to be taught as "the" way to multiply all polynomials, which is clearly not true. (As soon as either one of the polynomials has more than a "first" and "last" term in its parentheses, you're hosed if you try to use FOIL, because those terms won't "fit".) When multiplying larger polynomials, just about everybody switches to vertical multiplication, because it's just so much easier to use. If you want to use FOIL, that's fine, but (warning!) keep its restriction in mind: you can ONLY use it for the special case of multiplying two binomials. You can NOT use it at ANY other time!.
Simplify ( x - 4)( x - 3) .
So the answer is: x 2 - 7 x + 12 Using FOIL would give: "first": ( x )( x ) = x 2 "outer": ( x )(-3) = -3 x "inner": (-4)( x ) = -4 x "last": (-4)(-3) = +12 product: ( x 2 ) + (-3 x ) + (-4 x ) + (+12) = x 2 - 7 x + 12 .
Simplify ( x - 3 y )( x + y ) .
So the answer is: x 2 - 2 xy - 3 y 2 Using FOIL would give: "first": ( x )( x ) = x 2 "outer": ( x )( y ) = xy "inner": (-3 y )( x ) = -3 xy "last": (-3 y )( y ) = -3 y 2 product: ( x 2 ) + ( xy ) + (-3 xy ) + (-3 y 2 ) = x 2 - 2 xy - 3 y 2 .
Let me reiterate what I said at the beginning: "FOIL" works ONLY for the specific and special case of a two-term expression times another two-term expression. It does NOT apply in ANY other case. You should not rely on FOIL for general multiplication, and should not expect it to "work" for every multiplication, or even for most multiplications. If you only learn FOIL, you will not have learned all you need to know, and this will cause you problems later on down the road. I have seen too many students greatly hampered in their studies by an unthinking over-reliance on FOIL. Their instructors often never even taught them any method for multiplying other sorts of polynomials. For your own sake, take the time to read the next page and learn how to multiply polynomials properly. ( Full Answer )

# Why is the FOIL method not needed when multiplying two binomials?

It is only not needed if you know of another method. If FOIL is the only way you know to multiply two binomials, then it is definitely needed.

# Can you apply foil method for the product of two factors having three or more terms each?

Strictly speaking, no. Because the acronym refers only to the First and Last terms. Even the O and I refer to the first and last in each bracket. What you need to do is to multiply each term in the first factor by each term in the second factor. It may be helpful to draw a grid to make sure you'v…e got them all. In the following example, I have numbered, in the grid, the position of each term in the answer - you don't need to do that. A tick in the box is good enough. So (2x + 3y + 4z)*(5w + 6x + 9z) 3 terms * 3 terms so, before simplification, there must be 9 terms. I start with the first term in the first factor and multiply it by each term in the second factor. Then move to the second term in the first factor. The order does not matter, but doing it systematically means that you should not miss out a product. 10wx + 12x 2 + 18xz + 15wy + 18xy + 27yz + 20wz + 24xz + 36z 2 There are two xz terms which can be combined. Grid: 2x 3y 4z 5w 1 4 7 6x 2 5 8 9z 3 6 9 ( Full Answer )
