- 07-19-2018, 09:49 AMMathematicians (and calculator designers) restrict the definition of \sqrt{1} to 1 so that they don't have conflicts with the principles of equality,...47 replies | 702 view(s)

- 07-19-2018, 07:08 AMIt's transitivity (if a=b and b=c then a=c), a key characteristic of equality in mathematics There's also reflexivity (a=a) and symmetry (if a=b...47 replies | 702 view(s)
- 07-18-2018, 07:52 AMgrapes replied to a thread As the Universe looses space, it gathers time. so it must loose time to gather space. in Space Time and the Universe"The speed of light to the sixth power" is 7.2? So, speed of light is 1.3896...? What units is that? And for 7.2?4 replies | 40 view(s)
- 07-18-2018, 07:43 AMBut, 6 does not equal -3, and 5 does not equal -3 So, what is your answer. I gave you mine, "yes."47 replies | 702 view(s)

- 07-15-2018, 07:54 AMWe don't You just use a different definition. You even use a different definition of equality. For instance, in your definition, if A=-3 and...47 replies | 702 view(s)
- 07-14-2018, 12:13 PMYou're certainly using a different definition for the radical sign, that much is clear. You may not like the usual definition, but you're still...47 replies | 702 view(s)
- 07-14-2018, 01:40 AMYou use different definitions from everyone else, whosever they are. In what post? I couldn't find any post of mine where that appears.47 replies | 702 view(s)

- 07-03-2018, 01:10 AMEinstein gave a good answer for why the speed of light is squared in that equation. It has nothing to do with protons and neutrons, per se.9 replies | 98 view(s)

- 07-02-2018, 09:40 AMYes \sqrt{9} = +3 \sqrt{9} cannot also equal -3. Yes. If \sqrt{9} = +3 then taking the negative of both sides is -\sqrt{9} = -347 replies | 702 view(s)
