Why a slow song seems fast just after waking up?


Have you ever played a song right after waking up? If no, then please do. You will certainly agree with the title of this post.

As a matter of fact, after gaining access to media devices in my childhood, I observed this strange thing for days..later forgetting the whole thing.

So how’s this possible? I have two speculations in queue,

Speculation 1:

Recall the time when you heard that song first time, the speed you heard that time can be compared with nothing, but many repetitions later, a default speed is saved.

And it is natural for the brain to reset and go through a mental checklist every time you wake up from sleep.

Now when you wake up, although the song is in your memory but the timbre, rhythms, pitch etc are not yet fetched instantly. Hence our brain sort of behaves like its hearing few wave parts for the first time. And till the time it fetches it node by node, the wave line passes, making it to lose the details or in other words the song appears faster.

Incidentally, instrumentals seems less faster thus supporting above speculation.

Speculation 2:

It has been known that humans recall fatal events in ‘slow motion’ due to a reverse of this phenomenon i.e.; more details recalled to increase survival chance or slower overall recall because of a fixed recall speed.

The ‘grogginess‘ experienced upon waking might play a part as well. Thus we can blame evolution over here 😛

Another example of this is, sitting down and relaxing music seems faster, but if you go for a jog or begin any strenuous activity, the speed decreases. Thereby supporting this speculation.

But no matter what the speculations are, listening to our favorite songs right after waking up takes refreshments to another level.

so Happy listening 🙂


Why do shoelaces untie themselves and earphone cables tie themselves up?


Why do shoelaces untie themselves and earphone cables tie themselves up? And if that’s the case, can’t we just interchange them?

It actually because of Entropy [Entropy (order and disorder)] i.e.; Systems always tend to move to a state of higher disorder for more stability. Means with an average length of a earphone, there is a 50% chance that it will knot in your pocket or bag.

As per scientific studies it was concluded that the longer your cable, the higher the chances of it knotting, due to the face that ‘system’ in case of shorter cords will relatively less tends to instability. 


Though few factors will act as a catalyst such as,

for shoelaces, they are slick and/or round in shape. Round polyester or nylon laces are the slickest and hardest to keep tied. But it also depends on the whipping motion created while walking or the hems of your trousers / pants brushing against them etc.

for earphones, (or any bunch of long, flexible objects), as per knot theory, the linking in a number of places, with enough contact points, increases the chances for these objects getting into one of those ‘knot’ states or the more contact points, the more possible knotted states will exist.

Conclusion: Hence as per entropy and knot theory, a cord lesser than 50 cm would almost never tangle itself. But if the length goes beyond that, the probability shoots up till it gets flattened at 2 meters.

As a solution, you can use ‘untangle’ earphones or fabric cord earphones (like this one) which are a little costlier though. And for shoelaces, just google for reef knot, which is way stronger than the usual granny knot 🙂
