Kelebihan Laplace transform: kau boleh tahu sistem kau kat mana stabil kat mana tidak. Itu sebab kau tengok Bode plot, Nyquist plot, root locus etc etc.

Kekurangan: Kalau SISO, ok senang, bagus, mudah. Kalau MIMO, mampuih, baik pakai state-space.

On Laplace Transform:
Differential eqns biasanya susah nak solve. Laplace transform akan "tukar" diff eqn tu jadi algebraic eqn yang lagi senang nak "diuruskan". Analyze dalam algebraic eqn, lepas tu guna inverse Laplace balik supaya jawapan kau make sense dlm real world.

Apa tu Laplace dan apa kegunaannya dalam dunia kejuruteran?

Bagus soalan ni..

Sebelum saya menjawab, kita kene tau yang ada beberapa hasil kerje Encik Laplace ni ada beberapa contribution sebenarnya.

Antaranya adalah...

[Ihtesham Ali @ihtesham2005]

A 22-year-old graduate student in Kazakhstan got so angry at journal paywalls in 2011 that she built a pirate website holding 88 million scientific papers, and last month she turned the whole thing into an AI that lets you ask one question and get the actual research as the answer.

Her name is Alexandra Elbakyan, and the website is called Sci-Hub.

The AI she just launched is called Sci-Bot. It lives at https://t.co/6w0IBtOEYB and almost nobody outside academia knows it exists yet.

Here is the story, because it is one of the strangest things to happen in science publishing in the last 50 years.

Elbakyan was born in Almaty in 1988, the year the Soviet Union started to collapse. She taught herself programming at 12. She read Soviet science books that explained things her family used to call miracles. She got into computer security at university and graduated in 2009 with a degree she barely needed because by then she was already a serious hacker.

Alexandra moved to Moscow that fall. Then Germany. Then a research internship in the United States. She was working on brain-computer interfaces, the kind of research that requires you to read hundreds of papers a year just to keep up with the field.

And every single one of those papers was locked behind a journal paywall that cost between 30 and 50 dollars to read once.

She did the math. A graduate student in Kazakhstan could not afford to read science.

The first thing she did was learn how to get around the paywalls one paper at a time. She passed the trick around to other students. They asked her for papers constantly. She got tired of doing it manually.

So in September 2011, in three days, she wrote a script that automated the whole thing. A user pastes a DOI. The script logs in through a donated institutional credential. The paper comes back free. The website caches it.

The next person who asks for that paper gets it instantly because the previous request already saved a copy.

That was Sci-Hub. Three days of code. One graduate student. Done.

15 years later, the cache holds 88 million scientific papers. Almost every piece of scholarly literature published before 2020 is sitting on her servers. Researchers in 190 countries use it. Studies in Nature have shown that roughly half of all academic paper downloads worldwide now go through Sci-Hub, not the publishers who actually own the copyrights.

Elsevier sued her in 2015 and won a 15 million dollar judgment. She did not pay. The American Chemical Society sued her and won an injunction. She did not comply. Courts in India, France, Russia, and the UK have tried to block the domain. She just moves it. https://t.co/3sAWJzNe8I. https://t.co/tGIETesZ8i. https://t.co/H5WQ1f9lqR. The site has had over 20 domains and is still up.

Nature put her on its list of the 10 people who mattered most to science in 2016. The New York Times compared her to Edward Snowden. The Verge called her the pirate queen of science.

She has not been to the United States in over a decade because she would be arrested at the airport.

The Sci-Bot launch in April 2026 is the part that nobody is talking about.

She took the 88 million paper database and put a small language model on top of it. You ask a question in plain English. The model searches the entire shadow library, pulls the relevant papers, synthesizes an answer grounded in real citations, and links you to the full text of every source. Free. No login. No institutional credential. No paywall.

Three real scientists tested it for a Chemical and Engineering News article last month. They asked it medical and chemistry questions. The radiologist said the answer he got was usable. The chemist said the gaps in recent literature were obvious but the older science was solid. The publisher community is furious.

What she built is what the paid academic AI tools are trying to build. Except the paid ones are limited to what their parent publisher legally owns. Hers is limited to almost nothing.

Alexandra still lives somewhere in Russia. She does not give her address. She does not do video interviews. She gives talks over Skype with the camera off. She runs the largest illegal library in human history from a laptop and a donation page.

A graduate student who could not afford to read science built the system the entire scientific community now quietly depends on.

The publishers have spent a decade trying to shut her down.

She just shipped an AI that makes their entire business model outdated.

> I was on the job market for four years.

> I got 53 rejection letters.

> Then I joined the academic publishing industry as an editor.

> One day my boss said we should start an open access program.

> I said great idea.

> How much should we charge? He asked.

> $11,000 per article, I said.

> Nobody would pay this much money, he said.

> They will. I told him.

> I'm the only person in the room with a humanities PhD.

> I know what they'll pay.

> We launched the tier at $11,000.

> We called it Gold Open Access.

> We told researchers open access papers get more citation.

> As expected, researchers paid $11,000 per article.

> I made Elsevier $15 million in the first year.

> I got a $500,000 bonus.

> I bought a flat in Stockholm.

> Last week I introduced anther tier in our open accss program.

> I called it Premium Gold, cost only $25,000 per article.

> Elsevier CFO called it "exceptional revenue capture."

> My assistant said $11,000 it too expensive for researchers from low-income countries.

> I introduced the waiver program.

> The waiver requires a written application with a notarized proof that researchers can't afford to pay.

> Processing the application takes six weeks.

> Actually, it doesn't. I reject all applications.

> We mention the waiver in every panel.

> A senior researcher in India sent me an angry email.

> He included numbers on Indian academic salaries.

> I asked him to recommend his university to buy an institutional subscription.

> The university asked Education ministry for money.

> Education ministry got in touch with us.

> I quoted $715 million.

> My bosses said India would never pay such a price.

> I said they will. And they did.

> Researchers from univesities that rejected me submit their papers to Elsevier.

> I charge them extra $5,000 as my "grief fee."

> Last week, a graduate student emailed me asking why we sued Sci-Hub.

> I sent her our public statement on "sustainability."

> I didn't mention we'd also sued the Internet Archive that morning.

> Sci-Hub mirrors our papers for free.

> We sued them in New York.

> We sued them in Delhi.

> We'll sue them everywhere.

> The lawsuits are good for branding.

> They show we're "defending scholarly publishing."

> An APC is a fee.

> A fee is a service.

> A service has tiers.

> Tiers have premiums.

> Premiums signal prestige.

> Prestige justifies the fee.

> The fee justifies the bonus.

> The bonus is the metric.

> The metric is in my review.

> The review gets me promoted.

> I'll be Senior Vice President of Elseveir Open Access Strategy by Q3 2026.

> I'm going to introduce a new open access tier, Premium Gold Plus: $50,000 per article.

> We're launching three more journals this year.

> All open access.

> I'm speaking at the Frankfurt Book Fair in October.

GLOBUS - The Soviet Mechanical "SPACE GPS"

Before digital computers took over, Soviet spacecraft used something extraordinary: a fully mechanical navigation computer called Globus.

Installed in missions like Vostok and Soyuz, this device used a system of gears, cams, and rotating mechanisms to calculate the spacecraft's position in real time. As the capsule orbited Earth, Globus would continuously update-showing where the crew was above the planet.

No screens. No software.
Just pure engineering.

By factoring in orbital motion, Earth's rotation, and time, the system could accurately track ground position and even help determine reentry timing and landing zones.

It was reliable, self-contained, and didn't depend on external signals-making it perfect for the early space age.

A reminder that long before digital navigation... spaceflight was powered by clockwork precision.
