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

1) Lucretius argues for the existence of atoms...in 60 BC:

"Things cannot be created out of nothing or reduced to nothing. You may distrust my words since atoms cannot be seen with your eyes? Think however of all the tiny particles you do not see, but which we know must exist.."
2) "First of all the raging wind that whips the sea, overturns ships and scatters clouds. Sometimes it races across plains in a whirling tornado and knocks flat trees with a furious howl and menacing roar; all invisible particles of wind sweeping the land, sea and clouds..."
3) "Your clothes left by a surf-beaten shore grow damp. The same clothes, spread out in the sun, become dry. But did we see how the water soaked in, or how it departed with the sun's heat? The water must be distributed into tiny particles which the eyes cannot possibly see."

Today we celebrate Mohammad Abdus Salam’s birthday! He was one of the most influential theoretical physicists of the 20th century and the first Pakistani Nobel laureate in science. #TIL
Salam’s doctoral thesis on theory in quantum fields earned him international fame for its comprehensive and fundamental exploration of quantum electrodynamics.
This fed into his work in the 1960s when he devised the electroweak theory on unifying two of the four known forces of nature: electromagnetic force and weak nuclear force.
He hypothesized that weak force was transmitted by carrier particles — charged W and neutral Z bosons.

"Even as possible discoveries are announced, they arrive with debate & quickly fizzle because we cannot confirm #AlienLife has actually been discovered."

SFI/@ASU's @Sara_Imari argues for a more fundamental theory of #biology in @Slate's @FutureTenseNow:

slate.com/technology/202…
“What should a #UniversalTheory for life look like? It will have to account for features of #LivingSystems that no current laws of #Physics and #Chemistry can explain. That is, it will have to pinpoint processes in the universe that occur only because of life."
- @Sara_Imari

🔭✨🌀 Záhada galaxie BEZ TEMNÉ HMOTY vyřešena, odsává ji galaxie jiná...

Titěrná galaxie NGC 1052-DF4 udělala nedávno v kosmologii nemalé vlny. Její pozorování naznačilo, že má kolem sebe šokantně málo temné hmoty. Nynější studie naznačuje řešení záhady – temná hmota kolem NGC 1052-DF4 skutečně chybí, ale jenom protože ji UKRADLY GALAXIE OKOLNÍ. 💥
To zjistilo pozorování týmu MIREI MONTES učiněná s pomocí Hubblea. DF4 se totiž nachází blízko masivnější galaxie NGC1035. Právě tenhle větší budulínek z menší galaxie ZŘEJMĚ ODSÁVÁ viditelnou (baryonovou) hmotu i „neviditelnou“ temnou (nebaryonovou) hmotu. 🌬

Right, now, on to attoscience (which combines #quantum #physics with #ultrashort #lasers).
First, I dusted off an overview slide of my thesis presentation. Attoscience studies electron motion in bound states, ionization processes, charge transfer, and similar. Image
All of this happens on the time scale of attoseconds, 10⁻¹⁸ seconds (and sometimes femtoseconds = 10⁻¹⁵ s), which is almost unimaginably fast. In the short intro podcast with @the_ScienceTalk, I explained the comparison with the age of our universe.
To measure such fast dynamics we need an equally as fast tool, which is laser pulses of a few femtosecond duration or shorter. Because a lot of energy is compressed in a very short time, the peak power of these pulses can reach terawatts (similar to nuclear power plants). 😲☢️ Image

We must understand that #physics is not technology.
Lacs of #Physicsts teach d subject but don't know:
1. Big bang loaded mass with motion down to subatomic level. So PE & KE r wrong.
2. #Newton made time a physical quantity & gave us momentum mv.
3. But he mis-stepped next
Cont
Cont-
4. 1st Law of motion clearly states that non-accelerating bodies r at rest. So Earth & other bodies have 0 gravity.
5. From times immemorial ships have been moving in contravention to 2nd & 3rd Law.
6. Since g is zero big G being product of earth parameters is zero.
Cont-

7. Space being a choreography of curves can't allow linear pathways.
8. Motion can't happen without a center of motion.
9. Time & Length r wed to each other. T = 2 root L. Pendulum!
10. Buoyancy is wrong. A submerged body will sink if v let it go.
11. But loss of mass?

I am #grateful for the opportunity given by #IWS_Network to share my story, struggles and success in the voices without frontiers (VWF).
My name is Betelhem, most people call me Betty and I prefer it that way. I was born 27 years ago to a young couple in AddisAbeba, the capital of #Ethiopia. #IWSVoices 1/n Image
My mom and me rather look like sisters. Despite being a teenager when she got me, she sacrificed her whole life to raise me up. She made sure I had the best #education possible. I am forever grateful to my mom sis & do everything to make her and God #proud. #IWSVoices 2/n Image

The universe is everything from the tiniest particles, to the largest galaxies, to the very existence of space, time and life.

But, How did it all begin?

Time for a thread👇👇 Image
The origin of universe is the origin of everything.

Multiple scientific theories plus creation myths from around the world have tried to explain it's mysterious genesis.

However, the most widely accepted explanation is the "BIG BANG THEORY". Image
The Big bang theory states that the universe began as a hot and infinitely dense point, only a few milli metres wide, similar to a supercharged black hole.

About 13.7 billion years ago this tiny singularity violently exploded.

After some time in Twitter hibernation, I'm back with a microlesson on a topic I didn't have space to talk about in my book—sound!

Let's talk about what sound is, how it happens, and figure out how fast it is! #fluids #sound #physics
First things first. How does sound happen?

The first ingredient is matter. Air, water, even solids can transmit sound; but you can't have sound without one of these mediums. That's why you can't make sound in space—there's barely anything there!
An important thing to remember about matter is that isn't just a "blob" of stuff—it's actually a massive pile of tiny atoms/molecules bouncing around & off of each other in a complex, highly unpredictable dance.
