খানজাহান আলী: একজন সেনাপ্রধান, ধর্ম প্রচারক ও শাসকের গল্প

ঢাকা বিশ্ববিদ্যালয়ের ইসলামের ইতিহাস বিভাগের সহযোগী অধ্যাপক সুরাইয়া আক্তার বিবিসিকে বলছিলেন, খানজাহান আলী দ্বিতীয় ইলিয়াসশাহী শাসনের সময় অর্থাৎ ১৪ শতকের শেষের দিকে বাংলায় আসেন বলে মনে করা হয়।

বাংলাদেশের জাতীয় জ্ঞানকোষ বাংলাপিডিয়া বলছে, খানজাহান আলী ছিলেন 'একজন সুফিসাধক এবং বৃহত্তর যশোর ও খুলনা জেলার অংশবিশেষ নিয়ে গঠিত এলাকার আঞ্চলিক শাসক'।

Corona

On the basis of science and data, it has now been proven that the corona epidemic did not exist.

There were no additional deaths anywhere in the world.

But after the poisonous vaccination, countless people started dying.

And now the cause of death is not breathing problem but heart problem.

The Planck time is the time it takes for a photon to travel a distance equal to the Planck length: = 1.62 × 10-35 m. and is the shortest possible time interval that can be measured. With its associated Planck length, the Planck time defines the scale at which current physical theories fail.

How fast is Planck time?

Planck time is roughly 10−44 seconds. However, to date, the smallest time interval that was measured was 10−21 seconds, a "zeptosecond." One Planck time is the time it would take a photon travelling at the speed of light to cross a distance equal to one Planck length.

Planck length ....

The Planck length is the scale at which classical ideas about gravity and space-time cease to be valid, and quantum effects dominate. This is the 'quantum of length', the smallest measurement of length with any meaning.

And roughly equal to 1.6 x 10-35 m or about 10-20 times the size of a proton.

https://en.wikipedia.org/wiki/Discrete_calculus

1) The word calculus is a Latin word, meaning originally "small pebble"; as such pebbles were used for calculation, the meaning of the word has evolved and today usually means a method of computation. Meanwhile, calculus, originally called infinitesimal calculus or "the calculus of infinitesimals", is the study of continuous change.

2) Discrete differential calculus is the study of the definition, properties, and applications of the difference quotient of a function.

https://en.wikipedia.org/wiki/Infinitesimal

In mathematics, an infinitesimal number is a quantity that is closer to zero than any standard real number, but that is not zero.

Infinitesimals are a basic ingredient in calculus as developed by Leibniz, including the law of continuity and the transcendental law of homogeneity.
