Notre
Dame Cathedral drew more than 13 million visitors each year,
constituting one of the most important landmarks in Paris, second only
to the Eiffel Tower. Now, however, it faces years of reconstruction
before it can be brought back to its former glory — after April 15,
2019, nothing will be the same.
While the whole world stood
petrified, confronted by heart-wrenching images of the cathedral, brave
firefighters were struggling to salvage as much as they could of the
centuries-old relics. Indeed, a large chunk of the history of France
lies between the flying buttresses of Notre Dame, as the church has seen
more than 850 years of prosperity, turmoil, revolution, wars and peace.
The
foundations for the cathedral were laid in 1160, under the watchful eye
of Bishop Maurice de Sully. It’s location on the sacred eastern part of
the Île de la Cité (City Island), an area that has been dedicated to
worship since it was established as the heart of the city in Roman
times. Construction lasted for around 100 years.

Initially
constructed under the watchful eye of Maurice de Sully, the Bishop of
Paris, it was placed on a site used for worship of Jupiter since the
Roman settlers in Gaul. Before the magnificent cathedral, a humble
Christian basilica occupied this plot of sacred land.
Although
various modifications were introduced in the following centuries, the
cathedral’s rib vaults, external support pillars, huge rose windows
bathed in colors, and sculptural decorations, which include the
legendary gargoyles, were the product of the original building endeavor.

Making
a clear break from the former Romanesque style, Notre Dame set the bar
for future stone masons, legitimizing the coming of a new Gothic
aesthetic. The architects of Notre Dame had clear intentions of creating
the largest ecclesiastical building in France ― one that would cast a
long shadow over the roofs of Paris and prove France’s loyalty to God.
1851–70
Gothic
architecture, which originated in France, was characterized by
re-combining the already-known Romanesque elements into a more
innovative approach, enabling the builders to construct taller
cathedrals with the help of external support pillars.
It also
introduced a better understanding of natural light, and the way it can
be funneled into a church, thus creating a sense of unprecedented
divinity.
1860s
The
223-feet tall (67 m) towers, along with the 108-feet tall (32 m) have
appeared as a striking sight in medieval Paris, crowning the city as one
of the most important places of Christian pilgrimage in Europe. The
spire — which was sadly destroyed, along with two-thirds of the roof —
was originally built in the 13th century but was replaced during a major
restoration effort that took place between 1844 and 1864.

Notre
Dame has had a turbulent history. Most notably during the Huguenot
Riots of 1548 and the French Revolution of 1789 when the cathedral was
seen more as a sign of religious repression rather than a devotional
temple to God.
1922
Throughout
its history several attempts of restoration were made, perhaps the
biggest effort being between 1844 and 1864, when it was supervised by
Eugène Viollet-le-Duc. Viollet-le-Duc was a renowned French architect
who dedicated his life to restoring medieval structures, and the idea of
restoring the cathedral came in the wake of a literary phenomenon,
which sparked huge interest in the history of Notre Dame.

The
restoration was partly caused by the renewed interest for Notre Dame
that came along after Victor Hugo’s literary masterpiece, The Hunchback of Notre-Dame, was published, sparking popularity due to its detailed descriptions of the cathedral.
This article is for everyone who tries to will themselves invisible at the mention of blockchain.
Imagine you’re admitted to the hospital for an emergency surgery following a freak selfie accident
while on vacation on the other side of the world. Right now, there’s no
way for doctors to know your full medical history, allergies, or
current medications: All that information is stored in silos that you
can’t access from the outside. But what if your medical records were all connected and immediately accessible—while still being totally private?
Or imagine you’re an architect in Syria and need to flee because of
civil war. Your life savings might not be accessible. Your
certifications and licenses are sitting in a desk back home, and may not
transfer to the country you resettle in. What if you could immutably
prove your identity and qualifications? What if you could send money for free all over the world?
If you like those ideas, you should care about blockchain.
Blockchain is a technology that has the potential to disrupt many of
the legacy systems and centralized industries of today. Hold off on
letting your eyes gloss over: Even though you’re not a hack-happy
crypto-bro, this next tech revolution needs all of us to take part at
the start.
The first step to caring is understanding that blockchain is just behind-the-scenes code. That’s all. You don’t need to be the person who knows how to code for it, but you do need to know the type of systemic changes it can affect. You do
need to know the industries it can disrupt. If you want the systems of
the future to work for you, include yourself in blockchain.
There are many blockchain-powered systems in the works that might already be a helpful addition to your life: Credit scores that aren’t controlled by a handful of high-risk, data-breach-prone companies; credible news systems that resist censorship; efficient power grids
that could lower your power bills. This isn’t incomprehensible hype:
These companies are relevant, understandable, and being built by people
who are not historically associated with tech.
With such great potential, we need to be more inclusive in how we talk about it, design with it, and create uses for it.
If people can’t understand, they can’t participate: As
of now, much of the language about blockchain is jargon-heavy and
intimidating: cryptocurrencies, ICOs, smart contracts, token sales, and
mining. The more people who can understand what blockchain is at a high level, the more people who can make it better, dream up applications to new systems, and accelerate its implementation. It needs to invite broad, diverse participation
and be accessible enough that non-experts can dream up potential
applications—otherwise, our products and systems will continue to work
well mostly for able-bodied white men.
The people who set the rules for a system have the power: It’s estimated that 93-95% of cryptocurrency assets are held by men. Why? Because technology and finance are traditionally male-dominated fields,
and cryptocurrency is a mix of both domains. The current rules and
methods for acquiring and using cryptocurrencies, no matter how well-intentioned
the larger motivation is for their existence, are baked with the biases
of their creators, and favor people like them. Part of the hype of
blockchain is its decentralization and democratization potential.
However, without a diverse set of people designing with it and
developing it, exclusion will be built into the base of many blockchain
applications.
Systems design depends on more than technology: We live
in an era where humanity, technology, and large-scale systems are
inextricably linked. Designers, community organizers, and
organizational-behavior experts are all versed in understanding the
dynamics of people and systems. What are the norms of a community? Who
are all the stakeholders? What do they need? What do they value? These
human-behavior questions are central to systems design and maintenance,
and because blockchain is potentially a massive disrupter to our current
systems, the most successful applications will incorporate insights
about human behavior. In order to avoid an explosion of trashy apps,
let’s get beyond the novelty of the medium, and begin to use it as a
tool with a purpose. Like a camera for a photo, a hammer for a nail, or a
tweezer for an eyebrow, blockchain is a tool for a system.
His Replacement Is Brilliant
Narrative memos have replaced PowerPoint presentations at Amazon.
Here are 3 reasons why.
In his 2018 annual letter, Amazon founder and CEO Jeff Bezos
repeated his rule that PowerPoint is banned in executive meetings. What
Bezos replaced it with provides even more valuable insight for
entrepreneurs and leaders.
In his letter, and in a recent discussion
at the Forum on Leadership at the Bush Center, Bezos revealed that
"narrative structure" is more effective than PowerPoint. According to
Bezos, new executives are in for a culture shock in their first Amazon
meetings. Instead of reading bullet points on a PowerPoint slide,
everyone sits silently for about 30 minutes to read a "six-page memo
that's narratively structured with real sentences, topic sentences,
verbs, and nouns."
After everyone's done reading, they discuss the topic. "It's so much
better than the typical PowerPoint presentation for so many reasons,"
Bezos added.
Artificial intelligence could spur the creation of a robot dictator
that could rule mankind forever, the billionaire Elon Musk says in a new
documentary.
"If one company or small group of people manages to
develop god-like superintelligence, they could take over the world,"
Musk said in the film.
The documentary Do You Trust This Computer? presents
a sobering look at the potential dangers of AI, including what could
happen if AI evolves to be smarter than humans and becomes its own
master.
