### Transcript

• 3. Do you understand nothing?
• 4. The History of Nothing (Zero)
• 5. Babylonians• First civilization to use zero• Used zero only as a placeholder, never on its own
• 6. Mayans• First civilization to actively use zero in equations• Used zero to create Long Count and yearly calendars
• 7. Indians• First civilization to describe the basic mathematical properties of zero• Described addition, subtraction, multiplication, and division with, by, to, and from zero
• 8. Math with Zero!• 2+0=2• 5–0=5• 4x0=0• 3/0 = ?Which one of these is not like the others?
• 9. The Powers of Zero!5² = 5 x 5 = 255³ = 5 x 5 x 5 = 125BUT! Why does: 5: = 1?5: = 5 ….???!!
• 10. The Powers of Zero (Cont’d)5² = 5 x 5 = 255³ = 5 x 5 x 5 = 125What about 5³ x 5²?5³ x 5² = (5 x 5 x 5) x (5 x 5) = 125 x 25 = 3125 there are five 5’s! So: 5³ x 5< = 5⁵ OR!5³ x 5< = 5=⁺< = 5⁵
• 11. The Powers of Zero (Cont’d – last slide on this I swear!)What about 5³/5<? Well …5³ = 5 x 5 x 55² = 5 x 5 DIVIDING THEM CANCELS TWO 5’sLeaving you with: 5 or 5¹. So 5³/5< = 5=⁻< = 5;Returning to our 5: issue: We know 5=/5³ = 5: 5³ = 5 x 5 x 55³ = 5 x 5 x 5 125/125 = 1
• 12. Division by Zero!
• 13. Original Solutions• Solution 1: X/0 = X• Solution 2: X/0 = Undefined (doesn’t work)• Solution 3: X/0 = InfinityCorrect Answer? Let’s look at each closer.
• 14. Solution 1: X/0 = X
• 15. Solution 1: X/0 = X (Cont’d) May I have zero slices please?
• 16. Solution 2: X/0 = Undefined (Doesn’t work)• The standard accepted solution in school and on calculators
• 17. Solution 2: X/0 = Undefined (Cont’d)A≠B 2≠3Ax0=0 2x0=0Bx0=0 3x0=0 2x0=3x0Ax0=Bx0 OR 2x0=3x0Ax0=Bx0 0 0 0 0 2=3A=B
• 18. Solution 3: X/0 = Infinity• Proposed by the Indian mathematician Bháskara• Initially rejected by the mathematical community because of flaws in the proof• Bháskara made an edit that would become the basis for quantum mechanics
• 19. Solution 4: 0/0 = Infinity• This solution works!Let’s say 0/0 = 746.345689 So if we multiply each side by 00 x 0/0 = 746.345689 x 00=0 Works no matter what number we0/0 = -45078932 set 0/0 equal to!0 x 0/0 = -45078932 x 00=0 Therefore 0/0 = ∞
• 20. Applications of Solution 4 Quantum Mechanics! Before you look for an electron, it isn’t in any one place – it exists only as a potential. So, it, theoretically, is in an infinite number of locations at any time.
• 21. Human ApplicationBefore you start anything, your speed –how fast you are moving towards yourgoal – is infinite.
