how about now we learn about temperature, let me give you some anomaly.
do you know why this happen? it’s because google decided to convert every temperature calculation into kelvin. now let me enlighten you a bit. in asia, especially in indonesia, people here use celcius to determined the temperature of its surrounding unlike american that uses fahrenheit instead. but celcius is only a position of the scale whereas kelvin can be used as a mathematic computation.
0C + 0C = 273.15 K + 273.15 K = 546.3 K = 273.15 C
The problem is that “degrees C” is overloaded here, to mean both a position on a scale, and the size of a unit on that scale, with no conventional short way of distinguishing which one you mean (which is one reason Kelvin was invented, since things aren’t ambiguous if you put absolute zero at 0 K).
this calculation the same as when you adding two averages number. it’s entirely nonsensical.
let’s see another example.
"5 C warmer than 30 C"
= 30 C + 5 C
= 303.15 K + 5 K
= 308.15 K
= 35 Cyou can add temperatures differences, you can add a temperature difference to a temperature, but you can’t add two temperatures because it’s useless as temperature addition is not commutative.
anyway it’s meaningless to add temperatures when the zero level is at +273. It’s like adding years relative to 2010 years ago – it would be meaningless to add this year – 2010 – with (say) 1666 – the year of the Great Fire of London. It’s meaningful to take differences (the Great Fire happened 344 years ago), but not to add. (Unless we converted to some kind of absolute time units e.g. years since the big bang)
but funny thing happen when you try to search it in wolfram alpha, I guess wolfram did a better job in calculating temperature than google did.
PS : I need to buy one of those thermometer to study about this temperature anyway.
