The Milankovitch Cycles - Science Feed

By

As you know, our earth completes a revolution every year and that's when we celebrate New Year. Likewise, there are cycles that affect out planet's long term climate condition. 

Milankovitch Cycle was hypothesised by the Russian scientist Milutin Milankovitch 1920. In this, he said that the long term climate changes are affected by the change in Earth's relative position to the Sun. According to him, Eccentricity, Obliquity and Precession of the planet are the factors of this that change over long period of time. Ice ages are estimated to be because of this. 

Eccentricity means the planet's orbit shape. This changes over time like increasing or decreasing. It has been found that it has been slowly decreasing over the period of the 100,000 years. 

Obliquity is the tilting of planet over its axis of rotation. This normally results in changes of seasons. It is slowly decreasing over the span of 41,000 years.

Precession is the wobbling of the planet over its rotating axis more like a spinning top. This is due to the gravitational tension on Earth because of Sun and Moon.

Because of these small changes on climate, this has long term effect. But, it is not clear that Milankovitch Cycle has impact on global warming. 

That's all about MIlankovitch Cycle. There will be more writing in this article coming later on. Thanks and Follow and Subscribe to our blog for more.

How does a NPU, Neural Processing Unit, works? - Science Feed

By
A NPU (Neural Processing Unit), also knows as AI accelerator, is a computing unit specially designed for the running artificial intelligence and machine learning models efficiently and effectively on a single motherboard with other computing units.  There has been significant rise in the use of NPUs in personal devices like smartphones, laptops, PCs etc. to do personalized recommendations and offline AI processing.  NPUs are capable of parallel processing, low precision arithmetic, hardware acceleration.  These have silicon architecture to kind of simulate the human brain working like human where instruction set of AI efficiently ran. NPUs are not for computing traditional problems as it lacks important physical capabilities. Because of these, AI systems are able to learn faster without wasting time and energy. The parallel computation feature give wings to matrix operations ease, activation functions of neural networks, dot product.  NPUs have got dedicated compute ...

What is Dark Energy? - Science Feed

By
There are different forms of energy. But, there has been speculation of an hidden form of energy that has been kind of hiding from us which constitutes a large part of our universe.  The universe has been found to be expanding faster than the speed of light. The traditional form of energy that we have found has been to be not able to provide that much of push. So, there must be something. This type of energy is called Dark Energy. Dark Energy is that form of energy that is not understood by us but it is fundamental in nature and drives the process of the universe. In Theory of General Relativity, there is concept of cosmological constant which says there is a negative of gravitation or empty space that is all over the interstellar space.  The researchers of DES and others have found that the universe is expanding not alone of known form of energy but some mysterious form of it. This is also related to Big Bang. Dark energy is told to be constituent of 68 to 70% of total univer...

Quantum Computer at Google solves real world problem 13,000x faster than current Supercomputers - Science Feed

By
On 22 October 2025, Google announced that they have solved a real world problem using their Quantum Echoes algorithm that did the work 13,000 times faster than current supercomputers.  This was the first time it has ever done where they used out of order time correlator OOTC algorithm. This  algorithm is verifiable since it can be ran again and again to get consistent result. They have released a scientific paper over this where they were able to do study of molecular structure using their latest Willow quantum computing chip. This chip used 105 qubit arrays to simulate the molecular behaviour. In this task, they disturbed one qubit from the simulated structure which lead to the formation of butterfly effect inside kind of like wave. This was first done in forward operations. After this, they ran the same operation but from the reverse side.  Both the sides waves start interacting with each other and give useful insights about the quantum nature.  According to Google...
