A female astrophysicist who shared a story about a man who was rude to her for carrying two laptops at the airport has ignited a discussion about gender bias.

Amber Roberts is an astrophysicist and an artificial intelligence program director.

She decided to share an interaction she had with a man at airport security when she was travelling.

Taking to Twitter, she wrote:

*I take out both of my laptops at airport security* Random guy: *scoffs* “What do you need 2 laptops for?” Me: “Well one is for my astrophysics work and one is for my artificial intelligence work.” #priceless #WomenInSTEM #womenintech #ai #GirlBoss​

The tweet received hundreds of thousands of likes and began to trend on Reddit, where it ended up on a forum about gender bias in tech industries.

Robert followed up her initial tweet with a thread about gender bias.

“I am now trending on r/Iamverysmart,” she began.

Men and women weighed in on the issue on Twitter.

Some men debated about whether it was a gender issue or simply that two laptops appear strange.
