Tutoring in your own home, at your own convenience

Today's schooling doesn't allow room for individual learning, which means that students who don't suit the pace of the whole class can fall between the cracks. If students aren't achieving at the level they are capable of their learning can stall, leading to boredom and frustration. Their confidence can suffer and they won't enjoy school as much as they should.

I can help. I offer personal tutoring in a range of subjects, and can provide students with the skills and confidence they need to achieve their potential.

I'm based in Auckland and will come to your home at a time that suits you, for maximum convenience and maximum learning. Because the home is a familiar environment, it's where the student is the most comfortable - this is as important part of enjoying learning.

Tuesday 17 April 2012 - New gravity map released

At the end of last month the European Space Agency released a new geoid of Earth's gravity. The geoid is what the oceans' surface would look like if there was just ocean and no tides, weather, etc. Because of differences in Earth's gravity in different locations, what we call "sea level" actually varies by almost 200 metres around the planet. The lowest point at -107m is just off the southern tip of India where there is a mysterious gravity well. The highest point is at +85m.

What we call "down" is actually perpendicular to the geoid, not directly toward Earth's centre. What we call "horizontal" also lies on the geoid, not at 90° to the direction of Earth's centre.

Monday 5 March 2012 - Raspberry Pi, a $48.26 computer

British charity Raspberry Pi Foundation has announced the Raspberry Pi. "The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming."

Yes, a Raspberry Pi can play full 1080p MPEG-4 video, and be plugged into any TV with an RCA video connector or an HDMI port (and sound over HDMI is supported). There are two models; Model A has one USB port, Model B has 2 USB ports and an ethernet port. "Beyond this, mice, keyboards, network adapters and external storage will all connect via a USB hub." It boots from an SD card and will run off 4xAA cells. More information on the features is here. The Model B is available here. The slightly cheaper and lower specification Model A will be available later this year.
