پاکستان کی لبرل و سیکولر اشرافیہ کو “ #تصوف “ کا بہت شوق ہے مگر انہیں عمران خان صاحب و تحریک انصاف کا تصوف پسند نہیں ہے ۔ دونوں گروہ قدیم اور اصل صوفیاء کے یہ اقوال پڑھیں اور آنکھیں کھول لیں (بحوالہ قول الجمیل از شاہ ولی اللہ ) Image
جس #تصوف #سلوک و #طریقت کو مزاروں ، چلوں اور وظیفوں میں ڈھونڈا جاتا ہے وہ تصوف اور وہ صوفی صرف خدمت خلق میں ہے

#سعدی_شیرازی

طریقت بجز خدمت خلق نیست

بہ تسبیح و سجادہ و دلق نیست

“طریقت، خدمت خلق کے سوا کچھ اور نہیں ہے”

“یہ تسبیح اور سجادہ اور گدڑی سے (میں) نہیں ہے”
تصوف ، سلوک و طریقت یونیورسٹیوں سے نہیں درد دل سے ہے سائنس کو مذہب سے الگ رکھیں دونوں کو برباد کریگی یہ ملاوٹ - تصوف و سلوک و طریقت صرف یہ ہے 👇

#خواجہ_میر_درد

درد دل کے واسطے پیدا کیا انسان کو

ورنہ طاعت کے لیے کچھ کم نہ تھے کر و بیاں

#Vedic texts suggest that #Hindus originally did not worship idols and build #temples, and it is quite likely that both Hindus and #Buddhists got the idea from the #Greeks.
#India accounted for 33% of the #World economy in AD 1.
#China's share was 26% of World GDP.
India was by far the World's economic superpower at that time.
#Indians sold textiles, spices and demanded precious metals in payment.
Not a year passed in which #India did not take 50 million sesterces away from #Rome.

There are three concepts that are at the core of machine learning:
data, a model, and learning.

Machine learning is about designing algorithms that automatically extract valuable information from data.

#ml #machinelearning #ai #artificialintelligence #Maths #Mathematics Image
The emphasis here is on “automatic”, i.e., ml is concerned about general-purpose methodologies that can be applied to many datasets, while producing something that is meaningful.
Data
Since machine learning is inherently data driven, data is at the core data
of machine learning.

The goal of machine learning is to design general-purpose methodologies to extract valuable patterns from data, ideally without much domain-specific expertise.

"#Economics in #Nouns and #Verbs"

Below, we share key excerpts from SFI External Prof W. Brian Arthur's (@Stanford, @PARCinc) latest, available at arxiv.org/abs/2104.01868, which we recommend for its elucidation of key blind spots in economic thinking & how to address them...
"Different means 'see' differently—often they reveal different versions of the same object. #MRI looks at body parts and reveals soft tissue structure; #CT scanning looks at the same body parts and reveals bone structure. There is no 'correct' version of internal body parts."
"#Mathematics is powerful in #economics—and necessary—but I don’t believe that it is suited to describing all that is interesting in an economy. In fact I don’t believe that there is any privileged way to view the economy. There are useful ways and less useful ones."

A few days back I held a @joinClubhouse conversation with an interesting gathering of #mathematics teachers and other #educators, and I did talk about #ethnomathematics.
The conversation generated a heated debate among them.
A thread #Culture #Maths #KnowledgeProduction
In the discussion, I also mentioned African Humanism as new enlightenment based on the endogenous & indigenous techniques and methods to generate knowledge in the #GlobalSouth.
Someone was so upset and felt attacked by this.
Others by my expression #decolonize the #decolonization
My point was and still remains not necessarily to antagonize the Western way of knowledge production but put aside and to mainstream our traditional techniques that fallen in disuse and take into formal education as another way of producing knowledge.

Does #risk management involve a lot of maths?
Yes and No!

It's a well-rounded discipline.
For #Actuarial, Insurance, Financial Engineering, Quantitative Finance and Investment Management, Mathematical Trading, and Financial Risk Assignments, you might require a lot of Maths and Statistics.

Is like asking whether we need milk and sugar for making ice cream ;)

Believe it or not, the Batman is real. Well, it’s more like a man who was the Bat. This character was beloved by those who knew him. While the story of Robert Douglas Lancey starts in the woods of NH, #OTD in 1944 it takes a dark turn in the unlikeliest of places. A #WWII thread. Image
On July 20th, 1941, Robert donned a crazy costume at @camptakodah. He looked like a cartoon bat. His job was to surprise the campers and have them chase him. But, no one could catch Robert no matter how hard they tried. He was too fast, too good, and too clever to be caught. Image
Robert, a dedicated Boy Scout and respected summer camp leader, with a distinctive long face and a “pug nose,” would go on to win a great many personal challenges that he faced well beyond the sanctity of a place that truly is “friendly to all.” Image

IS HISTORY ALL TRUE SERIES: when even the #Calendar isn’t❓

THE REAL ACTUAL SOLAR CALENDAR:
*Based on the noble science of #Astronomy; the sister science to #Geometry, #Mathematics and the “almost” lost numerical science mysteries. Which was mastered in
“ancient” times, but is close to forgotten, in these “modern” days. Go figure❗️😄☦️

Navigation of the oceans was man’s first real great step of personal evolution, here on earth. The earliest of discovered sciences; #astronomy; allowed men to navigate through
routes to known territories; or to discover new ones, by the endlessly reliable positions of the stars and constellations, in the night sky. Hence; much diligent study, over who knows how many epochs, and great civilizations; was an esteemed scholarly pursuit. And led to a vast

(I forgot) Yesterday is the 194th birthday of one of the greatest mathematicians Bernhard Riemann was born in Breselenz in 1826. Student of Gauss, Riemann published work in the fields of analysis and geometry.
1/n
#Mathematics #Riemann
His biggest contribution was likely in the field of differential geometry, where he laid the groundwork for the geometric language later used in Einstein’s General Theory of Relativity.
1/2
Among many other achievements, he made groundbreaking discoveries regarding the distribution of prime numbers. The “Riemann Hypothesis” is one of the most famous unsolved problems in #Mathematics
