  • Difficult for them though isn’t it? In reality, they can’t do anything but line up behind any plausible peace proposal that is brokered by another country. We’re not in a position to be the mediators this time.

    They can’t come out and say they will do something specific (unless it’s just words, strongly condemn etc) because it will be hung around their necks when it doesn’t happen.


  • That’s true, however people can be junior doctors for a surprisingly long time so you can see why they are pissed off! I assumed it was the first 3 years after graduation or something until one of my friends who is a doctor explained it to me.

    Junior doctors are qualified doctors in clinical training.

    They have completed a medical degree and can have up to nine years’ of working experience as a hospital doctor, depending on their specialty, or up to five years working and gaining experience to become a general practitioner (GP).












  • Interesting, I think it’s different for structural engineering because you’re doing calculations in accordance with a code of practice and the spreadsheet needs to be adapted to tweak the inputs and outputs of a standard formula and apply it slightly differently for different bridges / structural arrangements. I’ve written loads of spreadsheets that have been used and adapted by other people in my company, I honestly don’t think they are that difficult to understand (or people wouldn’t have been able to build on them and adapt them).

    I can see that lab software is quite different, especially if you have very well defined procedures and you are repeating exactly the same test again and again with the same inputs and outputs.



  • In structural engineering (bridge design etc), we use quite complicated spreadsheets for calculations; a database wouldn’t be the right tool for that job. We use excel because everyone knows how to use it and it’s easy to print to PDF and see the inputs and outputs and any graphical summaries you have added. Using a spreadsheet makes it easy to check and easy to adapt/change when you want to do a slightly different calculation next time.

    I’ve tried building spreadsheets of similar complexity in libreoffice and it’s true they are very slow in comparison and more prone to crashing.

    Libreoffice works well for some tasks and I enjoy using it at home but honestly if I tried to use it at work it would cut my productivity significantly. I’m probably using it more intensively than most people though.




  • Yeah I don’t disagree with what you’re saying, we don’t put fresh grads on jobs without adequate supervision on the design side either. On both sides of the “fence” you need the experience to produce a good product; the two jobs are different and should be complimentary.

    The schemes I have worked on that have been the most successful have had the designer and contractor working together closely from an early stage to produce something that works well, drawing on the past experience of both to anticipate potential issues and design them out.

    Personally it took me about 6 years before I felt I was good at design. Experience really does count.


  • That ship was about 100,000t.

    There’s a fairly crude equation in the American bridge engineering standard that relates impact load to the mass of a ship, which is:

    P =√(DWT) ±50%

    Where DWT is the deadweight tonnage, and P is the impact load in meganewtons.

    So in this case P=315MN ±50% which is 315000kN or 31500 tonnes of force…

    For comparison, I’m working on a project where we’re going to build a new concrete bridge on the ground next to where it needs to go (under a railway) then wait until we have a planned week with no trains running and push it into position using jacks. That bridge is a 60m long 20m wide 8m high concrete box with 1m thick walls and top and bottom slabs, and we think we will need about 30MN to install it (one tenth of the impact load from that ship).

    So yeah… that’s quite a hit.
