@wildncrazyguy "However, icing a sprain does still have some benefits, such as reducing initial inflammation so that you can start to do what can actually help - moving the muscles."
Um, that's pretty much what icing is supposed to do. No one is advised to keep icing a sprain past a couple of days
I'm not entirely sure what they found from the article, because I thought I learned something about photon absorption in the chlorin ring way back in undergrad, but regardless, the idea that a single photon is sufficient to trigger the photosynthetic process is absolutely fascinating, and the idea that we can track that is even more so.
I came here to complain about the measurement too, so I'm converting it.
The Asteroid is 850m across, which is about 28 blue whales long, or 283 bottlenose dolphins, or 1118 golden retrievers.
I was too lazy to do this manually, so I punched it into GPT 4. I did verify that the math, indeed, checks out.
Edit: Sorry for the edits. GPT assumed the tusk in the calculation, so I had to ask it to remove the tusk for this math to check out properly.
The size of a narwhal: Narwhals typically range in size, but males on average can be about 4.7 meters long.
The length of a banana: The length of a banana varies, but a typical banana is about 18 centimeters long.
Let's start by converting the asteroid size from narwhals to meters.
If 99 narwhals equal 850 meters, then one narwhal would be approximately 850/99 ≈ 8.59 meters.
Now, this doesn't match the usual size of a narwhal that we have (4.7 meters). There might be a discrepancy in the calculation, but for the sake of this exercise, let's use the size provided.
Now, let's convert the asteroid size to bananas.
850 meters is equivalent to 850 * 100 = 85000 centimeters.
If 1 banana is 18 cm, then:
85000 cm / 18 cm/banana ≈ 4722.22 bananas.
So, the asteroid is approximately 4722 bananas long, if we base the calculation on the given size of the narwhal. But please note, this is a fun approximation and might not be precise.
To begin with, we need to know the average volume of a narwhal. According to the National Oceanic and Atmospheric Administration (NOAA), the average length of a male narwhal is about 16 feet (4.9 meters) and its weight is about 1,800 kg. The volume of a narwhal can be calculated by using the formula for the volume of a cylinder, where the radius is half of the length.
Volume of a cylinder = π × r^2 × h
Radius = length/2 = 4.9/2 = 2.45 meters
Height = 16 feet ≈ 4.9 meters
Volume of a narwhal = π × 2.45^2 × 4.9 ≈ 96.3 cubic meters
Next, we can estimate the volume of a banana. The volume of a banana may vary depending on its size and shape. For simplicity, let's assume that a medium-sized banana has a volume of 100 cubic centimeters (cc) or 0.1 liters.
Now, we can divide the volume of a narwhal by the volume of a banana to get an estimate of the number of bananas needed to fill the narwhal's volume.
Number of bananas = Volume of narwhal / Volume of banana
Number of bananas ≈ 96,300,000 cc / 100 cc = 963,000 bananas
Therefore, it would take around 963,000 bananas to fill the volume of one narwhal, although this estimate may not be very accurate due to the assumptions and approximations made.
One key to the seeming advantage of IBM’s quantum computer is quantum error mitigation, a novel technique for dealing with the noise that accompanies a quantum computation. Paradoxically, IBM researchers controllably increased the noise in their quantum circuit to get even noisier, less accurate answers and then extrapolated backward to estimate the answer the computer would have gotten if there were no noise. This relies on having a good understanding of the noise that affects quantum circuits and predicting how it affects the output.
Just when I think I have a handle on what quantum computing is and start to build a mental model of it, they come up with stuff like this that makes me question myself. I can sort of see how, if the noise had a non-uniform impact on the state of the system how such a thing could be possible. But the fact they actually have managed to do it is amazing to me!
Quantum computing is just so damn weird. The computational model (well, models; there's a few) is just so different that it's hard to wrap your head around
