Lev

Theremin: The world's first electronic musical instrument, made by Russian physicist Lev Sergeivitch Termen in 1920.

Father Sergius, in the short story by the same name by Lev Nikolayevich Tolstoy, cut off his finger to prevent himself from falling into temptation.

Lev Nikolayevich Tolstoy rightly believed that the Kingdom of God is within us.

What Lev doesn't know is that, nowadays, many of the things he chews on and even the air he breathes at home might contain high levels of toxic chemicals with adverse effects on his health.

This is eight-month-old Lev. As with all babies, he puts everything in his mouth.

The Russian poet Lev Rubinstein has died after being hit by a car in Moscow.

If attending to your childhood wounds and responding with kindness feels selfish, it is important to remember that compassion for oneself often makes people more compassionate to others, Lev said.
