Google Doodle celebrates ‘father of fiber optics’ Charles K. Kao

His landmark research laid the groundwork for the internet.

In 1966, a Chinese-born electrical engineer and physicist named Charles K. Kao co-authored a proposal that would revolutionize global communications and lay the groundwork for the internet we know today.

Along with collaborator George Hockham, Kao proposed using thin glass fibers to transmit data across long distances, replacing the bulky copper wires then in use in telecommunications. Though initially rejected, his proposal would transform communications technology and the industry as a whole.

To highlight Kao’s contribution to technology, Google will honor the engineer on Thursday with a Doodle celebrating his 88th birthday. The animated Doodle depicts Kao, widely known as «the father of fiber optics,» using a green fiber laser to transmit data from one end of the Doodle to the other.

Born in Shanghai on Nov. 4, 1933, Kao studied English, French and the Chinese classics before moving to England to study electrical engineering. After earning a bachelor’s degree, Kao went to work at Standard Telecommunication Laboratories in Harlow, England, while he was working toward a doctorate in electrical engineering.

At the time, glass fibers could carry light pulses for telephone signals only 20 meters (65 feet) before nearly all the light dissipated. But Kao’s 1966 landmark paper Dielectric-Fiber Surface Waveguides for Optical Frequenciessuggested it would be possible to transmit light signals more than 100 kilometers (62 miles) across a fiber of ultrapure glass.

Kao and Hockhamnoted in their conclusion that «a fiber of glassy material» of a specific construction «represents a possible practical optical waveguide withimportant potential as a new form of communication medium.»

Four years later, inspired by Kao’s vision, a group of researchers produced the first ultrapure fiber.

Kao’s landmark research allowed the rapid expansion of broadband communications through the hundreds of millions of miles of fiber optic cable that deliver massive amounts of data around the globe in a split second. For his work, Kao would share the joint Nobel Prize in Physics in 2009.

Kao would go on to oversee implementation of fiber optic networks worldwide and focus on education in the 1980s, serving as vice chancellor of The Chinese University of Hong Kong and founding Hong Kong’s Independent Schools Foundation.

Kao died in 2018 at the age of 84.

Answers for today’s Strands puzzle

These are the answers that tie into the theme. The goal of the puzzle is to find them all, including the spangram, a theme word that reaches from one side of the puzzle to the other. When you have all of them (I originally thought there were always eight but learned that the number can vary), every letter on the board will be used. Here are the nonspangram answers:

  • WAND, CHARM, AMULET, POTION, INCANTATION, CAULDRON.

Today’s Strands spangram is WIZARDRY. To find it, look for the W that’s three letters to the right on the top row, and wind down.

Quick tips for Strands

#1: To get more clue words, see if you can tweak the words you’ve already found, by adding an «S» or other variants. And if you find a word like WILL, see if other letters are close enough to help you make SILL, or BILL.

#2: Once you get one theme word, look at the puzzle to see if you can spot other related words.

#3: If you’ve been given the letters for a theme word, but can’t figure it out, guess three more clue words, and the puzzle will light up each letter in order, revealing the word.

Turn Your Pet Photos Into Cute iPhone Emoji in a Few Easy Steps

You already have hundreds of photos of your pets so you might as well make them into emoji.

I love my dog, Cinnamon Toast Crunch. She’s brown and white and loves to go on walks and I take every opportunity to show her to the world. And with the Live Stickers iPhone feature, I can turn photos of her into emoji and stickers, and then text them to everyone I know.

Apple introduced Live Stickers in iOS 17 as an evolution of the tap-and-lift feature from iOS 16, which lets you cut out subjects from photos and Live Photos. Now, by saving those cutouts as emoji and stickers of pets, family and friends, you can send endless cuteness to others.


Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.


Here’s how to transform your photos into emoji and stickers to send in Messages and other apps.

How to make Live Stickers and emoji from pictures

1. Open your Photos app.
2. Tap the photo you want to turn into an emoji or sticker.
3. Tap and hold the item in the photo you want to turn into an emoji or sticker until you see the white outline.
4. Tap Add Sticker.

Your iPhone will then add the Live Sticker to your Stickers drawer and appear in your emoji keyboard. If you tap the new sticker, you’ll be given the options to RearrangeAdd Effect or Delete it. Tapping Add Effect will let you add an effect to your sticker, like a white outline, to make it look even more like a sticker. 

The next time you go into Messages, you can use your new sticker as an emoji by tapping the emoji keyboard in the bottom-left corner of your screen, tapping the folded-over circle and tapping the emoji you want to use.

According to Apple, you can use your new Live Sticker anywhere you can access emoji. I tried to use my Live Stickers on the messaging app Slack, but they wouldn’t appear in the app. I also couldn’t access my Live Stickers in some third-party apps, like TikTok, so you might run into some issues when using your Live Stickers outside of Apple apps and devices.
