steve Stepping into Giant Shoes
Step into those giant shoes and find your own stride, With a four-trillion-dollar legacy to guide.
steve Swipe through key milestones to learn how Tim Cook led Apple for fifteen years.
steve Cook's mastery of global logistics allowed Apple to manufacture hundreds of millions of iPhones annually with unmatched efficiency.
Warehouse wizardry: When Tim Cook first joined Apple in 1998, he reduced the time Apple's computer inventory sat in warehouses from a full month to just two days.
steve Tim Cook officially became Apple's CEO in August 2011, amidst intense public skepticism about whether he could replace a creative visionary.
A person or thing that succeeds another in a position, office, or role. In August 2011, Tim Cook became the successor to Steve Jobs as chief executive of Apple.
Which university did Tim Cook attend to earn his Master of Business Administration (MBA) degree?
Would you prefer a charismatic visionary or an organized operations expert as your boss?
What was Tim Cook's job title at Apple immediately before he was promoted to CEO in 2011?
How did critics initially describe Tim Cook's leadership style compared to Steve Jobs' style?
When Steve Jobs resigned due to failing health, what month and year did Tim Cook officially become Apple's CEO?
How did Tim Cook drastically improve Apple's supply chain efficiency when he first started?
In what year did Tim Cook originally join Apple as the Senior Vice President of Worldwide Operations?
What was the approximate market value of Apple when Tim Cook took over as CEO in August 2011?
steve QWERTY Keyboard Design
To stop the typebars from jamming, Sholes laid out QWERTY keys, spreading out the letters to slow down the fastest typing hands.
steve Smooth out the corners of shapes to discover why app icons are secretly squircles.
steve The Math of the Squircle
It's not a rounded corner with a sudden bend, it's a superellipse curving smoothly to the end.
steve Danish designer Piet Hein popularized the superellipse in the 1960s to solve urban planning and furniture design challenges.
Superellipse traffic: In 1959, Stockholm used a superellipse to design a major traffic roundabout, proving the shape solves both math and traffic jams.
steve A rounded rectangle abruptly transitions from a straight line to a sharp circle arc, whereas a squircle curves continuously.
A closed geometric curve with symmetric properties that sits between an ellipse and a rectangle. French mathematician Gabriel Lamé first described this geometry in 1818 before its adoption in modern design.
What is the mathematical name for the family of shapes that includes the squircle?
Why does a traditional rounded rectangle look slightly broken to trained designers?
What is the main geometric difference between a squircle and a rounded rectangle?
What exponent value in the superellipse equation creates a perfect mathematical squircle?
Who was the Danish designer who popularized the superellipse in urban planning and furniture?
Which city used a superellipse to design its Sergels Torg public square in 1959?
What engineering concept ensures light reflections flow smoothly across car bodies and laptop corners?
Who first mathematically defined the superellipse family of shapes in 1818?
steve MEMS Accelerometers
Microscopic silicon bends with gravity, spinning your screen as you tilt it.
steve Accelerometers measure acceleration, treating the constant pull of Earth's gravity as continuous movement.
Microscopic airbags: The sensor that rotates your screen was originally designed in the 1990s to trigger car airbags during a crash.
steve The technology keeping your screen upright was originally invented to deploy life-saving car airbags.
What does the acronym MEMS stand for in smartphone sensor technology?
What physical material is primarily used to etch the microscopic gears and combs inside phone sensors?
Which industry first popularized the mass production of tiny silicon accelerometers in the 1990s?
What mathematical tool do phones use to prevent natural hand shakes from accidentally rotating the screen?
How many directional axes do modern smartphone accelerometers measure to determine orientation?
When your phone is lying completely flat on a table, what acceleration force does its accelerometer measure?
What electrical property changes when the microscopic fingers inside an accelerometer bend?
Which smartphone, released in 2007, popularized the auto-rotating screen for the general public?
